Question 1170353: a man sitting on 22.5 m high storey building measures the angles of elevation of a telecom mast directly ahead of him as 43'. He measures the angle of elevation of the mast when he is 52m in the front of the building on the horizontal ground as 70'
A calculate the height of the mast
The distance between the building and the mast Answer by mananth(16946) (Show Source):

AB = x/tan 40
tan 70 = (x+22.5)/52
52 * tan 70 -22.5 =x= AB tan 40
AB = 52 * tan 70 -22.5/ tan 40
AB = 143.45 m
Find x from AB = x/tan 40
