Mar 25, 2019 Admin #3 M MarkFL Administrator Staff member Feb 24, 2012 13,736 If you know the lengths of two sides of a triangle (we'll call them \(a\) and \(b\)), and the angle \(\theta\) subtended by the two sides, then the area \(A\) of the triangle is given by: \(\displaystyle A=\frac{1}{2}ab\sin(\theta)\) Can you proceed?
