Question

the poles of equal height are standing opposite to each other on eitther side of the road which is120feet wide from a point between them on the road the angles of elevation of the top of the poles are 60 and 30 respectively find the height of the poles and the distance of the point from the poles
​

Answer 1

Step-by-step explanation:

Let the height of each pole is H feet. Similarly, from right triangle Δ CED, H = (120 - x) tan 60°. ⇒ x = 90 feet. Hence, from equation (1) we get, H = x tan 30 = 51.96 feet.
