The angle of elevation of the top of a building from a point Z on the ground is 50°. If the height of the building is 124 m, find the distance from Z to the foot of the building.

A.

147.78m

B.

104.05m

C.

161.87m

D.

192.91m

Correct answer is B

From the diagram above; Tanθ=oppadj

tan50° = 124d

d = 124tan50

therefore, d = 104.05m
