Question

From the top of a building, 30.15m high, the angle of depression of a point on the ground level 25.88'm from the base is B° find B​

Answer 1

49.36 degrees to the nearest hundredth.

Explanation:

In the right angled triangle formed the adjacent side is 25.88 m and the opposite = 30.15 m.

So tan B = 30.15 / 25.88 = 1.16499

So m < B = 49.36 degrees.
