Question

Deshaun is looking up at a flag that is 50 feet away from him at an angle of elevation from ground level of 35°
What is the flagpole’s height, x, and the distance between Deshaun and the top of the flagpole, y?(1 point)
Responses

x=61.04 ft.
and y=35.01 ft.
x equals 61.04 ft. and y is equal to 35 point 0 1 ft.

x=35.01 ft.
and y=35.70 ft.
x equals 35.01 ft. and y is equal to 35 point 7 0 ft.

x=35.01 ft.
and y=61.04 ft.
x equals 35.01 ft. and y is equal to 61 point 0 4 ft.

x=71.41 ft.
and y=87.17 ft.

Answer 1

Use right-triangle trig with adjacent = 50 ft and angle = 35°.

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

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