Question

A boy observes that the angle of elevation of the top of a tower is 32 degrees.He then walks 8m towards the tower and then discovers that the angle of elevation is 43 degrees.Find the height of the tower.

Answer 1

d = h cot(32º)

d - 8 = h cot(43º)

8 = h [cot(32º) - cot(43º)]

h = 8 / [cot(32º) - cot(43º)]
