∠1 and ∠2 are vertical angles. ∠2 has a measure of 63°.
What is the measure of ∠1 ?
Enter your answer in the box.
Vertical angles are formed when two lines intersect. The measure of the ∠1 when ∠1 and ∠2 are vertical angles is 63°.
What are vertical angles?Vertical angles are a pair of angles formed when two lines intersect each other, these angles are always opposite to each other and measure the same.
We know about the vertical angles, therefore, if the pair of angles ∠1 and ∠2 are vertical angles, then the measure of the two angles is equal.
Now, as it is given that the measure of the ∠2 is 63° and ∠1 and ∠2, therefore,
∠1 = ∠2 = 63°
Hence, the measure of the ∠1 when ∠1 and ∠2 are vertical angles is 63°.

How to find the surface area of certain 3 dimensional shapes
circle O has a circumference of 132 feet. what is the approximate area of the circle?
You can use the given circumference of 132 feet to find the radius using the formula C=2πr. Once the radius is found to be approximately 21 feet, use the formula for the area of a circle, being A=πr², to calculate an area of approximately 1386 square feet.
Explanation:To find the area of a circle when you know the circumference, you can use the formula for the circumference of a circle, which is C = 2πr (C is the circumference and r is the radius). From the circumference, we can find the radius.
Let's rearrange the formula for r: r = C / 2π . Plugging in the given value, r = 132 / 2π approximately equals 21 feet.
Next, we use the area of a circle formula A = πr² and plug in the radius to calculate the area. Here, A = π * (21)^2 that gives us an area of approximately 1386 square feet.

if ABC and GEF are congruent by the ASA criterion, which pair of angles must be congruent
The pair of angles that must be congruent for the given pair of congruent triangles are ∠CAB and ∠GEF.
The ASA criterion states that two triangles are congruent if two angles and the included side of one triangle are equal to the two angles and the included side of the other triangle.
In the figure, we have:
∠ABC = ∠GEF (given)
∠ACB = ∠EGF (included angles)
AC = EG (included side)
Therefore, by the ASA criterion, triangles ABC and GEF are congruent.
The other possible pairs of congruent angles are:
∠ACB and ∠FEG
∠CAB and ∠EGF
∠ABC and ∠GFE
However, none of these pairs of angles are included angles.
Therefore, the only pair of congruent angles that must be congruent is ∠CAB and ∠GEF.

A window that is in the shape of a semicircle has a diameter of 28inches. find the area of the window. Round to the nearest tenth
Final answer:
The area of the semicircle shaped window is approximately 307.7 square inches when rounded to the nearest tenth.
Explanation:
The student has asked to find the area of a window in the shape of a semicircle with a diameter of 28 inches. To calculate the area of a semicircle, we first find the radius of the full circle, which is half the diameter, and then apply the formula for the area of a circle, A = πr², before halving it since we want the area of a semicircle.
Find the radius (r) of the semicircle: r = diameter/2 = 28 inches / 2 = 14 inches.
Calculate the area of the full circle: A = πr² = π * (14 inches)².
Halve the area to get the semicircle's area: Semicircle area = A/2.
Using the value of π as 3.14 and rounding to the nearest tenth: Semicircle area ≈ (3.14 * [tex](14)^2[/tex])/2 = (3.14 * 196)/2 = 307.72 inches².
Hence, the area of the semicircle shaped window is approximately 307.7 square inches when rounded to the nearest tenth.

A bicyclist was traveling from the village to the railroad station with a speed of 15 mph and he was coming back to the village with a speed of 10 mph. Find the distance from the village to the railroad station, if it’s known that it took 1 more hour for the bicyclist to get back to the village.
Since, a bicyclist was traveling from the village to the railroad station with a speed of 15 mph and he was coming back to the village with a speed of 10 mph.
Let the time taken in traveling from village to the railroad station be 't' hours
Distance is calculated by the formula:
[tex] d= s \times t [/tex]
So, the distance traveled from village to the railroad station is:
[tex] d=15 \times t [/tex]
Since, the time taken in traveling from railroad station to the village is 1 hour more = 't+1' hours
So, the distance traveled from railroad station to the village is:
[tex] d=10 \times (t+1) [/tex]
Therefore, distance traveled from village to railroad station is equals to the distance traveled from railroad station to the village.
So, [tex] 15 \times t=10(t+1) [/tex]
[tex] 15t=10t+10 [/tex]
[tex] 5t=10 [/tex]
So, t=2
Therefore, distance from village to railroad station = [tex] 15 \times t [/tex]
= [tex] 15 \times 2 [/tex]
= 30 miles.
Therefore, the distance from village to railroad station is 30 miles.
The distance from the village to the railroad station is 30 miles
Speed is the ratio of distance to time taken. It is given by:
Speed = distance/time
Let d represent the distance from the village to the rail station.
When Going at a speed of 15mph, let us assume he spent a hour, hence:
15 = d/a
d = 15a
When coming at a speed of 10mph, let us assume he spent b hour, hence:
10 = d/b
d = 10b
Therefore:
15a = 10b
But it took 1 more hour for the bicyclist to get back to the village, hence b = a + 1, hence:
15a = 10(a + 1)
15a = 10a + 10
5a = 10
a = 2 hours
d = 15a = 15(2) = 30 miles
Therefore, the distance from the village to the railroad station is 30 miles

Stephanie is going to summer camp. There are three cabins to which she could be assigned: Pine Cabin, Maple Cabin, or Spruce Cabin. She can be assigned either a top bunk bed or bottom bunk bed.
Answer: The probability of Stephanie being on a top bunk is 50%
The probability of Stephanie being in Spruce Cabin is 3333.3%
The probability of Stephanie being in Pine cabin on bottom bunk is 80%
Step-by-step explanation:
The probability of Stephanie being assigned to the Pine Cabin and a bottom bunk bed is 1/6.
We have,
To find the probability of Stephanie being assigned to a specific cabin and a specific bunk, we need to know the total number of possible outcomes.
In this case, there are 6 possible outcomes because there are 3 cabins and 2 bunk bed options for each cabin:
Pine Cabin, top bunk
Pine Cabin, bottom bunk
Maple Cabin, top bunk
Maple Cabin, bottom bunk
Spruce Cabin, top bunk
Spruce Cabin, bottom bunk
Let's say we want to find the probability of Stephanie being assigned to the Pine Cabin and a bottom bunk bed.
There is only one outcome that satisfies this condition (Pine Cabin, bottom bunk),
So the probability is:
1 outcome / 6 possible outcomes = 1/6
Therefore, the probability of Stephanie being assigned to the Pine Cabin and a bottom bunk bed is 1/6.
We can similarly calculate the probability for any other combination of cabin and bunk bed by counting the number of outcomes that satisfy the condition and dividing by the total number of possible outcomes.
Thus,
The probability of Stephanie being assigned to the Pine Cabin and a bottom bunk bed is 1/6.

the length of a rectangular garden is 5 feet longer than its width. The garden is surrounded by a 2-foot-wide sidewalk. The sidewalk has an area of 76 square feet. Find the dimensions of the garden.
Final answer:
By setting up equations based on the given information about the garden and the sidewalk around it, and then solving for the width, we find that the width of the garden is 5 feet, and its length is 10 feet.
Explanation:
Let's denote the width of the garden as w feet. Therefore, the length of the garden can be represented as w + 5 feet, since it is mentioned that the length is 5 feet longer than its width. Surrounding the garden, there is a 2-foot-wide sidewalk which affects the overall dimensions of the combined area (garden plus sidewalk). The width and length of this entire area would thus be w + 4 and w + 9 respectively, adding 2 feet on each side for the sidewalk.
To find the area of just the sidewalk, which is given as 76 square feet, we first calculate the area of the entire (garden plus sidewalk) rectangle, and then subtract the area of the garden. The equation for the area of the entire rectangle is (w + 4)(w + 9), and for the garden alone, it's w(w + 5). The difference between these areas gives us the area of the sidewalk:
(w + 4)(w + 9) - w(w + 5) = 76
Expanding and simplifying this equation gives us a quadratic equation to solve for w. Simplifying further:
w^2 + 13w + 36 - w^2 - 5w = 76
8w + 36 = 76
8w = 40
w = 5
Therefore, the width of the garden is 5 feet and the length is 10 feet (5 + 5).
