Question

The angle of elevation of the top of a tower from a point on ground which is 30 mtrs. away from the foot of the tower is 30°. Height of the tower is:(a) 10/√3 mtrs.(b) 10 × √3 mtrs.(c) 100 mtrs.(d) 20 mtrs.

Answer 1

Answer:

Step-by-step explanation:

tan A= opposite/adjacent

Therefore,

tan 30°= height /30

(1/√3) *30 = height

or height=(√3*√3*10)/√3

height=10√3 m
