Week 17 – precalculus 11

This week in precalculus 11 I learned about Sine Law.  I learned about trigonometry in grade 10 but this year we expand it a little bit more. Sine Law is to solve problems in triangles that are not right triangles. The formula for sine Law is:

Missing side: $\frac{a}{sin A}$ = $\frac{b}{sin B}$ = $\frac{c}{sin C}$

And

missing angle:$\frac{sin A}{a}$ = $\frac{sin B}{b}$ = $\frac{sin C}{c}$

Here is an example:
