Question

How to find the value of sin 108 degree

Answer 1

Step-by-step explanation:

The sin of 108 degrees is 0.95106, the same as sin of 108 degrees . To obtain 108 degrees multiply 108° by  π  / 180° = 3/5  π . Sin 108 degrees = sin (3/5 ×  π ).

Answer 2

sin 108 degree

sin (90+18) degree

We know that, sin (90+ θ) = cos θ

So, it equals cos 18 degree.

Value of cos 18 degree is whole square root of (10+2√5)/16
