A triangle has sides A, B, and C. If the angle between sides A and B is #(5pi)/12#, the angle between sides B and C is #(5pi)/12#, and the length of B is 6, what is the area of the triangle?
Since the triangle is isosceles height divides the base equally.
In other words the said triangle consists of 2 right angled triangles with base=
Therefore we can write
In a right angled triangle height
Therefore Area of the triangle
