Question

A tower subtends angles θ, 2θ and 3θ at three points A, B, C respectively lying on a horizontal line through the foot of the tower. Then, the ratio AB/BC equals

Answer 1

Correct option: (A)

Explanation: 

For the given statement, we can draw the figure like this

From the figure, we have ∠AEB = ∠BEC = θ

Hence, BE is the bisector of triangle AEC.

Now, using bisector theorem, we have
