The matrix [-0.8 -0.6
0.6 -0.8] (a 2x2 matrix)
represents a rotation. Find the angle of rotation (in radians).
This one has me stumped, any help would be appreciated. The answer is 2.5 radians but the approach is where I am lost.

I understand that is the rotation matrix, what I don't understand is how you come up with the final angle of rotation. Do you plug in the numbers into the corresponding thetas? Thanks again for the help. I would be more specific but I have to head to work. Any help would be appreciated.
