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.
147.78m
104.05m
161.87m
192.91m
Correct answer is B
From the diagram above; Tanθ=oppadj
tan50° = 124d
d = 124tan50
therefore, d = 104.05m
