Sine rule 
The three trigonometric ratios; sine, cosine and tangent are used to calculate angles and lengths in right-angled triangles. The sine and cosine rules calculate lengths and angles in any triangle.

Using sine curve to calculate obtuse angles
1. sin(C)/5.7 = sin(32)/3.1
2. sin(C) = (5.7 * sin(32))/3.1
3. sin(C) = 0.974367
4. C = 77°
5. Angle ACB is obtuse, therefore C must be 103°
