A triangle has sides A,B, and C. If the angle between sides A and B is #(2pi)/3#, the angle between sides B and C is #pi/6#, and the length of B is 2, what is the area of the triangle?
Sum of the three angles of a triangle
Hence the third angle
It’s an isosceles triangle with sides a & b equal.
When length 2 corresponds to
Area of triangle
