Question

Deshaun is looking up at a fl ag that is 50 feet away from him at an angle of elevation from ground level of
. What is thefl agpole’s height, x, and the distance between Deshaun and the top of the fl agpole, y?

35°
x = 35.01 ft. and y = 61.04 ft.
x = 35.01 ft and y = 35.70 ft.
x = 61.04 ft. and y = 35.01 ft.
x = 71.41 ft. and y = 35.70 ft.

Answer 1

Use the horizontal distance 50 ft and angle 35°.

x = 50·tan(35°) ≈ 50·0.70021 = 35.01 ft.
y = 50 / cos(35°) ≈ 50 / 0.81915 = 61.04 ft.

So the first choice (x = 35.01 ft and y = 61.04 ft) is correct.
