Question

2. Two poles of height ‘a' meters and 'b' metres are 'p'
metres apart. Prove that the height 'h' drawn from the
point of intersection N of the lines joining the top of each
ab
pole to the foot of the opposite pole is ab metres.
----
a+b
​

Answer 1

Step-by-step explanation:

Let AB and CD be two poles of height a and b metres respectively such that the poles are p metres apart i.e. AC= p metres. Suppose the lines AD and BC meet at O such that OL =h metres. Hence, the height of the intersection of the lines joining the top of each pole to the foot of the opposite pole is ab/(a+b) metres.
