Answer:
42.0°
Step-by-step explanation:
To compute the angle, we need the measures in compatible units. It can be convenient to convert feet to meters.
Tan = Opposite/Adjacent
tan(angle of elevation) = (building height)/(shadow length)
angle of elevation = arctan((62 ft)(0.3048 m/ft)/21 m) = arctan(18.8976/21)
angle of elevation ≈ 41.984°
The angle of elevation of the sun is about 42.0°.
