The sum of the interior angles of a triangle is $pi$ . The sum of the two given angles is $pi$ . This is a line, not a triangle. It has no area.

A triangle has sides A, B, and C. Sides A and B have lengths of 9 and 7, respectively. The angle between A and C is (7pi)/24(7pi)/24 and the angle between B and C is (17pi)/24 (17pi)/24. What is the area of the triangle?
