[answered] How to calculate alpha with Math.asin()?

Question

I searched in the internet and I found out that in a right-angle triangle alpha = arcsin(a/c) and in JavaScript you calculate arcsin with Math.asin().
But this function doesn't return an angle in degrees and I don't know how to turn it into an angle.
(This is the code I need it for:

Answer 1

alpha = arcsin(a/c) will give you the result in radians.
To convert this to degree, you have to multiply it by 180/Pi

alpha_deg = alpha_rad *180/Pi
