A vertical pole is 10 meters from a building. When the angle of elevation of the sun is 45º, the pole cast a shadow on the building 1 m high. Find the height of the pole
Answers
Verticle pole 10 m away from building at 45° Sun angle cast a shadow of 1 m high at building then Height of the Pole = 11 m
Step-by-step explanation:
A vertical pole is 10 meters from a building. When the angle of elevation of the sun is 45º, the pole cast a shadow on the building 1 m high
As angle of elevation = 45°
=> Tan 45° = Pole height / Shadow Length
=> 1 = Pole height / Shadow Length
=> Shadow Length = Pole Height
Building is 10 m away from Pole
and Shadow on building is 1 m height
Hence Shadow Length =10 + 1 = 11 m
Hence Pole Height = 11 m
