draw the quarter unit circle form the x to y axes. Then the line with an angle of 22 degrees w.r.t. the y-axis. it intersects the circle at the coordinate:

(sin x, cos x) where the argument of cos and sin is in degrees for convenience now.

now find x.

You know that if you flip around the axis i.e. you switch x and y you end up in the point (cos 22, sin 22) so we solve sin x = cos 22 and cos x = sin 22. thus x = 90 - 22 degrees.

Again this really isn't needed
