Question 995818
<font face="Times New Roman" size="+2">


The trick to this one is to recognize that the diagonals of a kite are perpendicular.  With the diagonals constructed, you have 4 right triangles consisting of two pairs of congruent right triangles (you can prove the right triangles congruent by HL).  Then the angles you want are the sum of one of the acute angles of one of the right triangles and one of the acute angles of the other right triangle.
