A flag pole is casting a 20ft shadow. the flag pole measures 16 ft. find the angle of elevation of the sun
1 answer:
Answer: 38.7°
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Tan α = opposite side / adjacent side
Where α is the angle of elevation of the sun (x), and the opposite side is the height of the pole, and the adjacent side is the length of the shadow.
Replacing with the values given:
Tan x = 16/20
x = arc tan 0.8
x= 38.7°
