Question

Let a vertical tower AB have its end A on the level ground. Let C be the midpoint of AB and P be a point on the ground such that AP = 2AB. If ∠BPC = β, then tan β is equal to:

6/7
1/4
2/9
4/9

Answer 1

Answer:

♠ The correct option is C.

Explanation:

tan (θ + β) = 1/2

and tan θ = 1/4

1/4+tanβ1−1/4tanβ=121/4+tan⁡β1−1/4tan⁡β=12

9 tanβ = 2

tan β = 2/9

Answer 2
