Question

An engineer on the ground is looking at the top of a building. The angle of elevation to the top of a building is 38°. The engineer knows the building is 300 ft tall. What is the distance from the engineer to the base of the building to the nearest whole foot? ✓ 384 ft 487 ft X 234 ft 185 ft

Answer 1

384 ft.

Explanation:

We know the opposite side of the triangle and we need the adjacent side.

So tan 38 = opposite / adjacent

= 300 / x

x = 300 tan 38

x = 383.98 feet.

Answer 2

My best guess is 384 ft

Explanation:

Tangent 38° = opposite side / adjacent side

Tangent 38° = 300 ft / x ft

The value of x from the equation is 383.98 ft. Thus, the engineer is 383.98 ft.

Rounding it up gives us 384 ft.
