Week 15 – Precalculus 11 – Sine Law

The sine law allows us to find sides and angles much easier. The image above shows the sine law which is basically a (side)/sin A (angle) = b (side)/sin B (angle) = c (side)/ sin C (angle).

lets say we have a triangle where a = ?, b = 17, c = 3 and A = 93, B = 55 and C = 32

to find a, we’d use the sine law as shown:
