| **Determine the height of the tower, the length of the shadow from which is 37.5 m, and the angle of incidence of the sun’s rays during the measurement is 60 °.**

To solve the problem, we use a picture, where AB is the height of the tower, BC is the length of its shadow.

Angle АСВ = 60о, angle BAC = 30о. The side that lies against an angle of 60 ° is greater

the side lying opposite the 30 ° angle exactly twice (60: 30 = 2).

Find the height of the tower: 37.5 × 2 = 75 m.

Answer: the height of the tower is 75 m.
