A triangle has sides A, B, and C. Sides A and B have lengths of 12 and 5, respectively. The angle between A and C is #(7pi)/24# and the angle between B and C is # (5pi)/24#. What is the area of the triangle?
First, you would find the third angle:
Well, the triangle is a rectangle triangle!
So you would get the area by simply multiplying the two sides A and B and dividing by 2:
