Answer:
Step-by-step explanation:
<h3>
If you are given the interior angle, just subtract that from 180 to get the exterior angle and then use the number of sides = 360 / exterior angle to find the number of sides. it's much easier. the number of sides is equal to 10. the sum of the interior angles is equal to 10 * 144 = 1440 degrees.</h3>
Answer:

Now , lets come to the question.
In a right angled triangle , let one angle be α (in place of theta) .
So , lets solve L.H.S.



= R.H.S.
∴ L.H.S. = R.H.S. (Proved)
