Alternately, you can recognize that the interior angles of a quadrilateral sum to 360 degrees, and again that the angles of a circle sum to 360 degrees.

So you already know two of the interior angles, and you know one others can be solves by (360-132)... and that the sum of those three plus 'x' = 360.

Hopefully that gives you enough to solve. (And I'd suggest solving it both way to check your answer. :-) )
