Question

when the angle of elevation of the sun is 42 degrees a flagpole casts an 18-meter shadow how tall is the flagpole to the nearest hundredth of a meter? Select an Option A: 13:38 B: 16:21 C:19:99 D:12:04

Answer 1

B. 16.21 m

Explanation:

When we draw a picture of the triangle, we should see that we need to use tan∅ to solve for height:

tan42° = h/18

18tan42° = h

h = 16.2073

h ≈ 16.21 m
