Question

What’s the correct answer for this ?
The traffic light is approximately _____ feet tall

Answer 1

Height = 21.78 ft

Explanation:

Tan θ = opposite / Adjacent

tan 40 = opposite / 20

where opposite is the part of the traffic light

0.839 × 20 = opposite

opposite = 16.78 ft

Now the total height of traffic light = 16.78 ft +5 ft

Total Height = 21.78 ft
