Question

the angle elevstion of a tower from a point on the ground which is 30m away from the foot of the tower is 30° find the hight of tower

Answer 1

Let the height of tower be x

tan 30° = x÷30 = 1/√3

⇒ x÷30 = 1/√3

⇒ x= 30/√3                             (Multiply by √3÷√3)

⇒ x = (30√3)÷3

⇒ x = 10√3
