1. The distance of the gate of a temple from its base is

   

times it height. Find the angle of elevation of the top of the temple.

Let us assume that PQ be the temple and R be the position of gate of the temple.

Let us assume “h” be the height of the temple,

Then, PQ = h

QR = Distance of the gate of temple from its base =

   

In ΔPQR,

=

=

=

So as we known,

   

  

Therefore on comparing,

Hence, the angle of elevation from the top of the temple is

   

.
