Question

The angle of elevation of the top of a building from a point on the ground, which is 30 m away from the foot of the building, is 30°. The height of the building is:​

Answer 1

Step-by-step explanation:

Let the height be x m

ATP

x/30= tan 30°

x/30=1/√3

x= 30/√3

x= 30 ×√3/√3×√3

x=30√3/3

x=10√3

x=10×1.732

x=17.32 m
