A 254-foot tall radio tower is located partway between a building and a tree. The angle of elevation from the base of the building to the top of the tower is 36°, and the angle of elevation from the base of the tree to the top of the tower is 62°.

Answers

Answer: here's your answer

485 ft

Step-by-step explanation:

step 1

Find the distance from the base of the building to the base of the radio tower

Let

x -----> the distance from the base of the building to the base of the radio

we know that

tan(36°)=254/x

x=254/tan(36°)=349.60 ft

step 2

Find the distance from the base of the tree to the base of the radio tower

Let

x -----> the distance from the base of the tree to the base of the radio tower

we know that

tan(62°)=254/x

x=254/tan(62°)=135.05 ft

step 3

Find the distance from the base of the building to the base of the tree

Adds the distances

349.60 ft+135.05 ft=484.65 ft

Round to the nearest foot

484.65 ft=485 ft

the total surface area of a hemisphere is 45
[tex]\pi\p[/tex]
CM square find its volume

Answers

Answer:

The volume of the hemisphere

V = 121.33086 cubic centimeter

Step-by-step explanation:

Step(i):-

Given that the total surface area of a hemisphere = 45π cm²

The total surface area of a hemisphere = 3π r²

Equating

3π r² = 45π

[tex]r^{2} = \frac{45}{3} =15[/tex]

r = [tex]\sqrt{15} = 3.87[/tex]

The radius of the sphere 'r' = 3.87

Step(ii):-

The volume of the hemisphere

[tex]V = \frac{2}{3} \pi r^{3}[/tex]

[tex]V = \frac{2}{3} \pi (3.87)^{3}[/tex]

we know that π = 3.14

[tex]V = \frac{2}{3} (3.14) (3.87)^{3}[/tex]

V = 121.33086 cubic centimeter

There is a building, if you are observing from the outside it looks like a parallelogram with one of the interior angles as 108. What will be the exterior angle that can be used for parking?

Answers

Answer:

Exterior angle to be used for parking is 72°

Step-by-step explanation:

I've attached an image of a paralelogram.

Now, we are told that from the outside it looks like a parallelogram with one of the interior angles as 108.

This means that the bigger angle internally would be 108°

Which from the attached image is angle B internally or angle D internally.

So, the interior angle observed will be either at point B or D on the parallelogram.

Now, the sum of angles on a straight line is 180°

Thus,

Internal angle D + External Angle D = 180

Internal angle B + External Angle B = 180

Internal angle is 108°

Thus;

External angle for either B or D = 180 - 108 = 72°

So the exterior angle to be used for parking is 72°

Solve the linear equation 29 - 3x = 5x + 5

Answers

Answer:

x = 3

Step-by-step explanation:

29 - 3x = 5x + 5

You want to have the variable of x on one side of the equation, so add 3x to both sides.

29 = 8x + 5

You want to isolate the variable of x, so subtract 5 from both sides.

24 = 8x

You want the variable x on its own, so divide both sides by 8.

3 = x

Check your answer by plugging x back into the original equation.

29 - 3(3) = 5(3) + 5

Solve.

29 - 9 = 15 + 5

Answers

Answer:

A. 200

B. Growth

C. 118%

Step-by-step explanation:

Answer:

Initial population size=200

The function represents a growth

Step-by-step explanation:

Equation to calculate population size after time, t

P(t) = 200(1.18)^t

To find initial population size we will take t = 0

P(0) = 200(1.18)^0

= 200(1)

= 200

To find that function represent growth or decay

P(1) = 200(1.18)^1

= 200(1.18)

= 236

Its means that after a year population increases. Hence, function represent growth.

By what percentage does the population change each year?

(236 - 200 / 200) * 100%

= 235%

Solve for x using Pythagorean Theorem. SHOW YOUR WORK.
24
30

Answers

Ok so let’s call the 30 a and call the 24 b.

So;

a = 30
b = 24
Find x

Formula;

a square + b square = c square
The c in this case is x.

So we are gonna transpose to make x the subject.

a square + b square = c square
x square = a square - b square

Now that x is the subject we are gonna solve for x.

x square = (30 square) - (24 square)
x square = 900 - 576
x square = 324

Now we are gonna find the square root of both sides.

x square = 324
x = 18

The square root of x square is x and the square root of 324 is 18.

Therefore x = 18

Step-by-step explanation:

The formula for a triangle is (L x W)/2. We plug this in so our first two sides are 24 and 24 square centimeters. The top side is 10 x 4, or 40 cm. The bottom side is 8 x 4, or 32 cm. The back side is 6 x 4, or 24 cm.

24 + 24 + 40 + 32 + 24 = 144 square cm

Answer:= 144cm²

Step-by-step explanation: 4x8 =32

4x6= 24

4x10= 40

8x6=48
