The flagpole is 20 ft high
Step-by-step explanation:
- Step 1: This forms a right angle and can be solved using the trigonometric ratio tan. Given the angle of elevation is 63°, and the length of the shadow (adjacent side) is 12 ft, find the length of the flagpole (opposite side).
tan 63° = opposite side/adjacent side
⇒ Height of the pole = adjacent side × tan 63°
= 12 tan 63° = 12 × 1.96 = 23.55 ft ≈ 20ft
