Question

Find x.
Round to the nearest tenth:
500 ft
S
у
x = [ ? ]ft

Answer 1

x = 437.3 ft

Explanation:

Angle of elevation = angle of depression = 29°

Reference angle = 29°

Adjacent side = x

Hypotenuse = 500

Applying trigonometric ratio, we have:

Cos 29 = x/500

Multiply both sides by 500

500*cos 29 = x

437.309854 = x

x = 437.3 ft (nearest tenth)
