In the above given triangle when `theta` = 0 then b=c
But when `theta` = 90 then d=0
Since d is the projection of b
How we can derive a generalised formula for d or c-d with respect to `theta`
Plese may kindly be elaborated.

Hello mfaisal
I can't see any working, so I'm not sure where you are getting stuck. Always show some steps so we can better help you.
The question seems a bit strange to me. Surely if `b=c`. then it won't matter what the angle `theta` is?

mfaisal did not reply.
A generalised formula would need to use trigonometry, I believe, something like
`tan theta = h/d`
I'm not sure there is any more "generalised" way to answer it.
