A triangle has sides A, B, and C. If the angle between sides A and B is #(3pi)/8#, the angle between sides B and C is #(pi)/2#, and the length of B is 12, what is the area of the triangle?
Lets take a look at the triangle.
The area of a triangle is given by the formula;
We are given the length of
We can solve for
So our area function becomes;
