Normally you would use one of the infinite series to calculate the sine of an angle.

Fortunately, though, this has already been done and was published in mathematical tables. Nowadays, though, you would simply use a computer or calculator.

Even more fortunately, sin(30 deg) = 1/2 so you don't even need a calculator.

What angle has a sine of 0.13?

To find which angle has a sine of 0.13, you calculate arcsin or sin^-1(0.13) =7.47 degrees 7.47 degrees has a sine of 0.13. There is also another angle , below 360 , has a sine of 0.13. Subtract 7.47 from 180. 180-7.47 = 172.53 degrees also has a sine of 0.13.


How do I find the length of the hypotenuse with one leg equalling 12 and the opposite angle being 30 degrees?

Rearrange the sine ratio of sine = opposite/hypotenuse: hypotenuse = opposite/sine hypotenuse = 12/sine 30 degrees = 24 Therefore the hypotenuse is 24 units in length.
