Question

Find the angle of elevation of the top of a tower from a point on the ground, which is 30 m away from the foot of a tower of height 10√ m.

Answer 1

Step-by-step explanation:

Distance between the 2 points is 30m and height of tower is 103

We have to angle of elevation. Let it be x

then tanx=30103=33=31

∴ x=30o

Answer 2

Distance between the 2 points is 30m and height of tower is 10
