Find x.<br> Round to the nearest tenth:<br> 28°<br> 350 ft<br> y<br> x = [ ? ]ft
Korolek [52]

Answer:

745.5 ft

Reference angle (θ) = angle of depression = angle of elevation = 28° (alternate angles are congruent)

Opposite side = 350 ft

Hypotenuse = x

Apply the trigonometric function, SOH:

Sin θ = Opp/Hyp

Sin 28° = 350/x

x = 350/Sin 28

x = 745.5 ft (nearest tenth)
