A man at ground level measures the angle of elevation to the top of a building to be 67°. If at this point, he is 15 feet away from the building, what is the height of the building. Round your answer to the nearest tenth.

The height of the building is 35.3 feet

Step-by-step explanation:

To find  the height of the building, we will follow the steps below:

Using trigonometric ratio to solve;

SOH CAH TOA

Sin Ф = opposite / hypotenuse

cosФ = adjacent /hypotenuse

tanФ=opposite / adjacent

From the diagram below, we have our opposite = h, adjacent =15 feet  and Ф = 67°

where h is the height of the building

The best formula to use is;

tanФ= opposite/adjacent

tan 67° = h/15

Multiply both-side of the equation by 15

15 ×tan 67° = 15× h/15

35.33778549 = h

h≈35.3 feet  to the nearest tenth

The height of the building is 35.3 feet

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
