Homework Statement
http://img10.imageshack.us/img10/9651/mathhelp.jpg
RED was given, BLUE was what I was able to find.
What is the area of the shaded part?
Homework Equations
Area of shaded part = area of two triangles + area of sector
The Attempt at a Solution
I was able to find the area of the two triangles easily enough, but I can't think of a way to find the the value of angle AOB without using a calculator. My idea was to find angles AOP and BOQ and subtract them from 180, but again, no calculators allowed.
