Hello,

You can Use Sin(3x) formula to solve your questions.

Sin(3x) = 3 sin(x) - 4 sin^3(x)

For sin10, x=10

Sin(30)=3sin(10) -4 sin^3(10)

1/2 = 3 sin(10) -4 sin^3 (10)

6sin(10) - 8 sin^3 (10)=1

Solve the equation (Take sin(10) as X , SO equ becomes 6X -8X^3=1)

Solve for x you will get Answer as 0.176

Similarly Try for sin20, sin15..!

Hope it helps you

Any further help,you can ask.

Thank yoy!!
