Use the sine law: 12.3 / sin 60 = 13/ sin b sinb = 13 * sin60 / 12.3 b = 66.25 the small triangle is iso, so |dw:1446756479566:dw| b' = 180 - b b' = 180 - 66.25 = 113.75

It's called the sine rule: |dw:1446756772888:dw| For any triangle ABC: \[\frac{ a }{ \sin(A) } = \frac{ b }{ \sin(B)} = \frac{ c }{ \sin(C) } = 2r\]

r is the radius of the circle passing through the heads of the triangle.|dw:1446756901245:dw|
