and \text{m}\angle V = 71^{\circ}.m∠V=71
∘
. Find \text{m}\angle U.m∠U.
Answer:
m∠U = 54.5°
Step-by-step explanation:
ΔUVW is an isosceles triangle. The angles opposite UV and VW are congruent.
That means m∠U = m∠W
Since the measures of the angles of a triangle have a sum of 180, then
m∠U + m∠W + m∠V = 180
m∠U + m∠U + 71 = 180
2 m∠U = 109
m∠U = 54.5°

From an angle of depression of 61 degrees, John
watches his friend approach his building while standing
on the rooftop. The rooftop is 17 m from the ground,
and John's eye level is at about 2m from the ground.
What is the distance between John's friend and the
building?
10.6
34.3
5.5
10.5
Answer:
10.53
Step-by-step explanation:
Given :
Height of building = 17m
John's eye level = 2 m
Total height (including eye level) = 17+2 = 19m
Angle of depression, θ = 61°
Let distance between John's friend and building = d
Using trigonometry :
Tan θ = opposite / Adjacent
Tan 61° = 19 / d
1.8040477 = 19 / d
d = 19 / 1.8040477
d = 10.53

Answer:
24
Step-by-step explanation:
A^2+b^2=c^2
In this case C^2 is solved and we have to solve for the remaining leg.
7^2+b^2=25^2
49+b^2=625
625-49=576
sqrt 576 = 24
The height is 24
A circle has a radius of 6 feet. Calculate the area of the
sector formed by a central 30° angle
Answer:
The area of the sector is 9.43 ft^2
Step-by-step explanation:
Here, we want to find the area of the sector with a central angle of 30 degrees
To do this, we use the formula below;
Area of sector = theta/360 * pi * r^2
theta = central angle = 30 degrees
r = radius = 6 ft
Thus, we have it that;
Area of sector = 30/360 * pi * 6^2
= 30/10 * pi = 3 * 3.142 = 9.43 ft^2

the following image is a trapazoid.if XW is congruent YZ and measaure of m = 72 degrees. calculate the measure of X
Answer:
opposite angle of trapezoid is supplementary
<Z+<X=180°
<X=180°-72°
<x=108°
is your answer
The required value of the measure of the angle x is 108°. Option A is correct.
The following image is a trapezoid. if XW is congruent to YZ and measure of m = 72 degrees. calculate the measure of X is to be determined.
The angle can be defined as the one line inclined over another line.
What is a trapezoid shape?A trapezoid is defined as a quadrilateral with one couple of opposite sides parallel. the sum of the opposite angles is 180. Only one pair of opposite sides should be parallel not all the sides if all sides are parallel then the shape became a rectangle or rhombus.
Since the sum of the opposite angles in trapezoids is 180°
so,
x + 72° = 180°
x = 180° - 72°
x = 108°
Thus, the required value of the measure of the angle x is 108°.

A dinner table is a perfect circle with a diameter of 8 feet
With dinner plates that each have a diameter of exactly 1 foot, how much of the tablecloth will be showing when the table is set for six people ?
Answer:
The area of the tablecloth showing is approximately 45.55 square feet
Step-by-step explanation:
The diameter of the dinner table, D = 8 feet
The diameter of each plate, d = 1 feet
The number of people at the dinner table = 6 people
The number of plates = 6 plates
The area of the table cloth, A₁ = π·D²/4
∴ A₁ = π × 8²/4
The area covered by the 6 plates, A₂ = 6·π·d²/4
A₂ = 6 × π × 1²/4
Let 'A' represent the area of the tablecloth showing when the table is set for six people, we have;
A = A₁ - A₂
∴ A = π × 8²/4 - 6 × π × 1²/4 ≈ 45.55 ft.²
The area of the tablecloth showing when the table is set for six people, A ≈ 45.55 ft.²

The variable r represents a value in the set (4,6,7,8). Which value of r makes 2(r-4) + 3=7 a true statement?
Answer:
r = 6
Step-by-step explanation:
2(r-4) + 3=7 becomes 2(r-4) + 3=7 if we subtract 3 from both sides:
2(r-4) = 4
Then r - 4 = 2, and r is 6.

A piling for a high-rise building is pushed by two bulldozers at exactly the same time. One bulldozer exerts a force of 1850
pounds in a westerly direction. The other bulldozer pushes the piling with a force of 3250 pounds in a northerly direction. What
is the direction of the resulting force upon the piling, to the nearest degree?
Answer: I got this answer from the internet hopefully this helps
Resultant force will act on 65° N of W.
Step-by-step explanation:
The direction of the resulting force upon the piling, to the nearest degree is gotten as; A = 60°
What is the direction of the resultant force?As given in the question one bulldozer exerts force of 1850 pounds in western direction and another pushes with a force of 3250 pounds in northern direction.
Now, we have to find angle A which is an angle between 1850 pounds of force and resultant force F.
Thus;
tan A= Force on North direction/ Force on west direction
tan A = 3250/1850
tan A = 1.7568
A = tan⁻¹1.7568
A = 60.35°
To the nearest degree is A = 60°
