Question

a boy observe the top of an electric pole at angle of elevation 45 the angle of elevation changes to 30 when he moved 10 metres away from the pole find the height of the electric pole ​

Answer 1

Answer:

Step-by-step explanation:

hey find the answer below

Answer 2

Answer:

5 (√3 + 1 ) m.

Step-by-step explanation:

let P be the height of the pole , H = HORIZONTAL DISTANCE FOR ANGLE 45

tan 45 = P/H , P = H

tan 30 = P/H +10 = 1/√3 ,  H(√3 - 1 ) = 10

H = 5 (√3 + 1 ) = P
