Answer:
angle of depression ≈ 53.8°
Step-by-step explanation:
the angle of depression is the measure of the angle from the horizontal downwards from the top of the flag pole.
this angle is alternate to ∠ A and is congruent to ∠ A
using the sine ratio in the right triangle
sin A = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{25}{31}[/tex] , then
∠ A = [tex]sin^{-1}[/tex] ( [tex]\frac{25}{31}[/tex] ) ≈ 53.8° ( to 1 d.p )
Angle of depression ≈ 53.8°
