Question

The angle of elevation of the top of a vertical tower from a point on the
ground is 60°. From another point 10 m vertically above the first,
angle of elevation is 45°. Find the height of the tower.​

Answer 1

Step-by-step explanation:

Let the height of the tower be h cm.

Now, In

And, In

Since, AB = CD, SO, equation (2) becomes,

Equating equation (1) and (3), we get,

Hence, height of tower will be 15 cm.
