Question

The upper part of a tree is broken over by the wind makes an angle of 30° with the ground and the
distance from the root to the point where the top of the tree meets the ground is 15m. The height of
the broken part is-
(A) 15 sin 30°m (B) 15 cos 30° m (C) 15 tan 30° m (D) 15 sec 30° m​

Answer 1

Answer: (D)

Step-by-step explanation:

    cos 30⁰ = 15 / h

⇒  h = 15 / cos 30⁰

⇒  h = 15 sec 30⁰
