A building casts a shadow 25 meters long when the sun’s angle of elevation is 45°. What is the height of the building?

1. 20 m
2. 25 m
3. 30 m
4. 50 m

Correct answer: 25 m

Solution

For an angle of elevation of 45°, tan 45° = 1. So height/shadow = 1, which means the height equals the shadow length. Therefore, the building’s height is 25 m.
