What is the measure of R to the nearest degree?
R measures 42.8 degrees, which is around average.
What are the properties of Triangle?The properties of the triangle are:
1. The sum of all the angles of a triangle (of all types) is equal to 180°.
2. The sum of the length of the two sides of a triangle is greater than the length of the third side.
3. In the same way, the difference between the two sides of a triangle is less than the length of the third side.
The sine rule states that for a triangle with sides a, b, and c opposite to angles A, B, and C respectively,
a/sinA = b/sinB = c/sinC
Using this rule, we can find the measure of angle R as follows:
a = ST = 30
b = RT = 35
c = RS
Let angle R be opposite to side b.
sinR/sinS = b/c
sinR/sin69 = 35/c
c = 35/sin69 x sinR
Now we can use the sine rule to find c:
a/sinA = b/sinB = c/sinC
30/sin69 = 35/sinR = c/sin42
c = 35/sinR x sin42
Equating the two expressions for c, we get:
35/sin69 x sinR = 35/sinR x sin42
Simplifying this equation, we get:
sinR/sin69 = sin42
sinR = sin69 x sin42
sinR = 0.672
Taking the inverse sine of both sides, we get:
R = sin^{-1}(0.672)
R ≈ 42.8 degrees
Therefore, the measure of angle R is approximately 42.8 degrees.

Spray from a lawn sprinkler makes a circle 40 feet and radius what are the approximate diameter circumference and area of the circle of the lawn watered
The approximate diameter of the circle is 80 feet, the circumference is approximately 251.327 feet, and the area is approximately 5026.548 square feet.
To find the diameter, circumference, and area of the circle watered by the lawn sprinkler, we can use the formulas:
1. **Diameter [tex](\(d\)) = \(2 \times \text{radius}\)[/tex]
2. **Circumference [tex](\(C\)) = \(2 \times \pi \times \text{radius}\)[/tex]
3. **Area [tex](\(A\)) = \(\pi \times \text{radius}^2\)[/tex]
Given:
Radius[tex](\(r\)) = 40 feet[/tex]
1. Diameter:
[tex]\[d = 2 \times r\]\[d = 2 \times 40 \text{ feet}\]\[d = 80 \text{ feet}\][/tex]
2. Circumference:
[tex]\[C = 2 \times \pi \times r\]\[C = 2 \times \pi \times 40 \text{ feet}\]\[C \approx 2 \times 3.14159 \times 40 \text{ feet}\]\[C \approx 251.327 \text{ feet}\][/tex]
3. Area:
[tex]\[A = \pi \times r^2\]\[A = 3.14159 \times 40^2 \text{ square feet}\]\[A = 3.14159 \times 1600 \text{ square feet}\]\[A \approx 5026.548 \text{ square feet}\][/tex]

WILL GIVE BRAINLIEST, 15 points-The daily number of patients visiting a dentist's office during one week are 8, 41, 35, 39, 36, and 42.
Which statement is true?
The mean, median, and mode are all appropriate measures of center.
Both the mean and median are appropriate measures of center.
The median is the only appropriate measure of center.
Both the median and mode are appropriate measures of center.
Answer: The median is the only appropriate measure of center.
Step-by-step explanation:
The statement is ''Both the median and mode are appropriate measures of center''. Actually, the three, that is, the mean, media and mode can be used to measure the central of tendency. But the MEAN has a problem, it can be Skewed by large values in the distribution/data. Assuming, the days of the week when patients visiting a dentist's office are;
Monday: 8, Tuesday: 41, Wednesday: 35, Thursday: 39, Friday: 36, and Saturday: 42.
And the mean of the distribution = 33.5. Most patients visit the dentist Tuesday to Saturday, where Saturday is the highest. The data is skewed. So, the MEDIAN will do the job perfectly.
For the mode; since we do not have; (1). two highest mode with the same value in the data provided and, (2). the highest value and the second to the highest values are not too far from each other. We can use the MODE here for measuring the central tendency.
===> CONCLUSION: (1). Assuming the data fails the two condition for mode, the most correct statement will be ''The median is the only appropriate measure of center".
===> (2). Also, for this data, the MEDIAN will be the only appropriate measure of center.

What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (2, -1) and (5, -10)
Now,
Since, The equation of line passes through the points (2, -1) and (5, -10)
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 10 - (-1)) / (5 - 2)
m = - 9 / 3
m = - 3
Thus, The equation of line with slope - 3 is,
⇒ y - (-1)= - 3 (x - 2)
⇒ y + 1 = - 3x + 6
⇒ y = - 3x + 6 - 1
⇒ y = - 3x + 5
Therefore, The equation of line passes through the points (2, -1) and
(5, -10) will be;

Sarah deposits $600 in a savings account that pays 2.5% per year. What is the minimum number of years it would take for the amount in her account to be more than $800, provided no more money is deposited in the account?
It will take at least 12 years for Sarah's $600 deposit at a 2.5% annual interest rate to grow to more than $800, assuming the interest is compounded annually.
To determine how long it will take for Sarah's $600 deposit at a 2.5% annual interest rate to grow to over $800, we can use the formula for compound interest: [tex]A = P(1 + r/n)^{(nt)[/tex], where:
A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).r is the annual interest rate (decimal).n is the number of times that interest is compounded per year.t is the time the money is invested for in years.Since the problem doesn't specify the compounding frequency, let's assume it's compounded annually for simplicity:
[tex]A = 600(1 + 0.025)^t[/tex]. We need A to be greater than $800.
To find the minimum number of years (t), we solve for t:
[tex]800 < 600(1 + 0.025)^t[/tex]
Solving for t gives us: t > ln(800/600) / ln(1.025).
Using a calculator, we find that t > 11.89.
Therefore, it will take at least 12 years for the amount in Sarah's account to exceed $800.

a 12-ft-long ladder is leaning against a wall and makes an 80 degree angle with the ground.how high up the wall does the ladder reach, and how far is the base of the ladder from the base of the wall? round to the nearest inch.,
Answer:
The ladder reaches 142 inches and the base of ladder is 25 inches far from the base of the wall.
Step-by-step explanation:
Let us draw a diagram for the given situation.
In the attached figure,
AB = the height of wall where the ladder reaches
AC = ladder
BC = distance of base of ladder from the base of the wall
In triangle ABC,
[tex]\sin C=\frac{AB}{AC}\\\\\sin80=\frac{AB}{12}\\\\AB=12\sin80\\\\AB=11.82[/tex]
And
[tex]\cos C=\frac{BC}{AC}\\\\\cos80=\frac{BC}{12}\\\\BC=12\cos80\\\\BC=2.08[/tex]
Now, 1 feet = 12 inches
Hence, 11.82 ft = 141.84 inches
and 2.08 feet = 24.96 inches
Therefore, in the nearest inches, we have
The ladder reaches 142 inches and the base of ladder is 25 inches far from the base of the wall.

Using your knowledge of circles, label the following on the given diagram: chord, tangent, radius, secant, point of tangency and diameter. Name a minor arc and a major arc.
In geometry, a chord, radius, diameter, tangent, secant, and the point of tangency are all parts related to a circle. A radius can also be an axis, a minor arc is the smaller arc between two points on a circle, and a major arc is the larger one. These terms help in understanding the properties and relations of lines to a circle.
In the context of circles in geometry, various terms define specific parts or aspects of a circle. Here's what each term represents:
A chord is a straight line segment whose endpoints both lie on the circle.The radius is a straight line from the center of the circle to any point on the circle. In other cases, it can form an axis which bisects a chord (as per a geometry theorem).A diameter is a chord that passes through the center of the circle, and it is also twice the length of the radius. Two radii forming a straight line constitute a diameter.A tangent is a straight line that touches the circle at just one point, this point is known as the point of tangency. A tangent is perpendicular to the radius drawn to the point of tangency.A secant is a straight line that intersects the circle at two points.A minor arc is the shortest arc connecting two endpoints on a circle, and a major arc is the longer arc connecting the same two endpoints. The length of an arc is proportional to the size of its associated angle at the center of the circle.
When drawing or labeling the parts of a circle, it's important to note these definitions. For instance, if given a diagram with a point on the circle labeled 'A' and the center labeled 'O', the segment OA would be a radius. If there's a straight line that touches the circle at point A and doesn't cross through it, that would be your tangent, and point A is the point of tangency. Any straight line through A that crosses through another point on the circle, say, point B, would be a secant, and the line OAB (if extended through O) would be a diameter. The arc's size determines if it is a minor or major arc, depending on whether it is more or less than half the circle's circumference.
