We’re going to use Cosine because the angle and sides given are Adjacent and Hypotenuse- which goes with the CAH part of SOH CAH TOA.
Cos(18) = x/25
Multiply both sides by 25
25cos(18) = X = 23.776
So x = 23.776 cm
I hope this Helps!
And that gives you... x = 23.776 cm

Use the triangle pictured to calculate the following measurements.
Perimeter: p = ___ units Semiperimeter: s = ___units Area: A ≈ ___square
triangle is 8 by 12 by 10
Answers
The perimeter of the triangle is the sum of its sides.
We have then:
P = 8 + 12 + 10
P = 30 units
Semi-perimeter:
In geometry, the semiperimeter of a polygon is half its perimeter.
s = P / 2
s = 30/2
s = 15 units.
Area:
Knowing the semiperimeter and the sides, the area is:
A = root (s * (s-a) * (s-b) * (s-c))
where,
s: semi-meter
a, b, c are sides.
A = root (15 * (15-8) * (15-12) * (15-10))
A = 39.68626967
A = 40 units ^ 2

A cylindrical container holding sugar has a height of 15 inches and a diameter of 4 inches. Which of the following is the closest to the volume of the sugar container?
A.
707 cubic inches
B.
94 cubic inches
C.
754 cubic inches
D.
188 cubic inches
Answers
say pi=3.14
h=15
d/2=r=4/2=2
so
v=(15)(3.14)(2)^2
v=(15)(3.14)(4)
v=(60)(3.14)
v=188.4
so answer is D
Using the formula V = πr²h, the volume of the cylinder is calculated as 188.4954 cubic inches, which can be rounded to 188 cubic inches, corresponding to answer choice D.
To calculate the volume of the cylindrical container holding sugar, we can use the formula for the volume of a cylinder, which is V = πr²h. Here, π is a constant (approximately 3.14159), r is the radius of the cylinder, and h is the height of the cylinder.
The diameter of the container is given as 4 inches, so the radius (r) is half of the diameter, which is 2 inches. The height (h) is given as 15 inches. Plugging these values into the volume formula, we get:
V = π(2 inches)²(15 inches)
= π(4 square inches)(15 inches)
= 60π cubic inches
Using 3.14159 as the value for π, the volume calculates to:
V = 60 * 3.14159 cubic inches = 188.4954 cubic inches
So, the closest estimate to the volume of the sugar container would be 188 cubic inches, which corresponds to answer choice D.

Let d represent the number of degrees in one angle of a regular polygon, and n represent the number of sides of the polygon to tessellate. which equation can be used to determine if the polygon will tessellate? 360° · n = d 360° · d = n 360° ÷ d = n n + d = 360° brainly
Answers
Answer:
360°/d = kn.
Step-by-step explanation:
To know if a regular polygon can tessellate, we divide 360 by the interior angle of the polygon and the result needs to be an integer, but not in all cases you get the number of sides of the polygon, you get a multiple of the number of sides. So, none of the options are correct, the correct would be
360/d = kn, where k is an integer.

Answer:
The dimensions are

[tex]10\frac{5}{8}\ in[/tex]
Step-by-step explanation:
we know that
If two figures are similar, then the scale factor is the ratio of its corresponding sides
step 1
Divide [tex]8\frac{1}{2}[/tex] by [tex]4[/tex]
[tex]8\frac{1}{2}=\frac{8*2+1}{2}=\frac{17}{2}\ in[/tex]

Find the largest complete enlargement
The scale factor is the smaller of the two previous values

What is FN ?
Answers
Or 16.81 or 16.8 simplified
Answer:
23.4 in
Step-by-step explanation:
The only side of SFN we know the measurement of is FS, which is 18.2. We see from the similarity statement that FS corresponds to QB, which is 14. This gives us the ratio
14/18.2.
From the similarity statement, we see that FN corresponds to QH; this gives us the ratio
18/x
Together this gives us the proportion
14/18.2 = 18/x
Cross multiplying gives us
14(x) = 18.2(18)
14x = 327.6
Divide each side by 14:
14x/14 = 327.6/14
x = 23.4
What are the angle measures of the triangle 6 12 6sqrt3?
Answers
Answer:
The measure of angle A is 30 degree, measure of angle B is 90 degree and measure of angle C is 60 degree.
Step-by-step explanation:
The measures of given sides are 6, 12, [tex]6\sqrt{3}[/tex].
According to the Law of Cosine:
[tex]\cos A=\frac{b^2+c^2-a^2}{2bc}[/tex]
Using Law of Cosine, we get
[tex]\cos A=\frac{(12)^2+(6\sqrt{3})^2-(6)^2}{2(12)(6\sqrt{3})}[/tex]
[tex]\cos A=\frac{216}{144\sqrt{3}}[/tex]
[tex]\cos A=\frac{3}{2\sqrt{3}}[/tex]
[tex]\cos A=\frac{\sqrt{3}{2}[/tex]
[tex]A=30^{\circ}[/tex]
Similarly,
[tex]\cos B=\frac{a^2+c^2-b^2}{2ac}[/tex]
[tex]\cos B=\frac{(6)^2+(6\sqrt{3})^2-(12)^2}{2(6)(6\sqrt{3})}[/tex]
[tex]\cos B=\frac{0}{36\sqrt{3}}[/tex]
[tex]\cos B=0[/tex]
[tex]B=90^{\circ}[/tex]
Therefore, measure of angle A is 30 degree and measure of angle B is 90 degree.
According to angle sum property, the sum of interior angles of a triangle is 180 degree.
[tex]A+B+C=180^{\circ}[/tex]
[tex]30^{\circ}+90^{\circ}+C=180^{\circ}[/tex]
[tex]C=60^{\circ}[/tex]
Therefore the measure of angle C is 60 degree.
The triangle with sides 6, 12, and 6√3 has angles of 30 degrees, 60 degrees, and 90 degrees.
Given a triangle with sides 6, 12, and 6√3, we can find the angles using the Law of Cosines.
First, we use the formula for the Law of Cosines,
c² = a² + b² - 2ab * cos(C).
Let a = 6, b = 6√3, and c = 12.
We substitute these values into the formula to find angle C,
cos(C) = (6² + (6√3)² - 12²) / (2 * 6 * 6√3)
Compute the values inside the formula:
6² = 36
(6√3)² = 108
12² = 144
cos(C) = (36 + 108 - 144) / 72
cos(C) = 0
Therefore, angle C = 90 degrees.
To find the other angles, we use the Law of Sines,
(sin A / a) = (sin B / b) = (sin C / c).
We already know C = 90°, so (sin C / 12) = 1/12.
For angle A,
sin(A) / 6 = 1/12
sin(A) = 6/12 = 1/2
A = 30 degrees
For angle B:
B = 180° - 90° - 30° = 60 degrees
Therefore, the angles of the triangle are 30 degrees, 60 degrees, and 90 degrees.

Exponential function:An exponential function is modeled by:
[tex]y(t) = y(0)(1 + r)^t[/tex]
In which:
y(0) is the initial value.r is the rate of change. If it is positive, it represents growth, and if it is negative, it represents decay.In this problem, the equation is:
[tex]y = 8700(1.04)^t[/tex]
Hence:
[tex]1 + r = 1.04[/tex]
[tex]r = 0.04[/tex]
Since r = 0.04 is positive, it represents a growth of 4%.
To learn more about exponential function concepts, you can take a look at https://brainly.com/question/24757163
Final answer:
The function y = 8700(1.04)^4 represents an exponential growth with a rate of increase of 4% per time period over four periods.
Explanation:
The given function is y = 8700(1.04)^4. This represents an exponential growth because the base of the exponent, 1.04, is greater than 1. To determine the percentage rate of increase, we observe that the base, 1.04, when written as a percentage, is 104%. This means that the amount increases by 4% over each time periodperiod. Since the exponent is 4, this growth occurs over four time periods. However, the overall increase is not simply 4% multiplied by 4, as exponential growth compounds wicompoundsth each time period.

The base of an isosceles triangle is 70 centimeters long. The altitude from the vertex angle to the base is 75 centimeters long. Find, to the nearest whole degree, the measure of the base angles of this triangle.
Answers
We get two similar right angled triangles ADC and BDC. For triangle ADC, AD = 35cm, DC = 75cm. Tangent of angle DAC can be written as:
[tex]tan(DAC)= \frac{CD}{DA} \\ \\ tan(DAC)= \frac{75}{35}= \frac{15}{7} [/tex]
Angle DAC is equal to tangent inverse of 15/7 which equals 65 degrees, rounded of to nearest whole degree.
Angle DBC = DAC = 65 degrees
Thus the base angles for the given isosceles triangle will be 65 degrees each, rounded of to nearest whole degree.
