Question 1049623
Having trouble finding all four degrees. I can always find the first but not all.
Solve for 2(theta) in the interval [0 degrees,720 degrees) Use your calculator

2(theta)=sin^-1(7/12)=35.685,144.315,395.685,504.315
-------------
Those 4 angles are the arcsin of 7/12.
If the angles = 2*theta, then divide by 2 to find theta.
