One concept that stumped me this week was using trig to find missing side lengths.

By using SOH CAH TOA and the following steps it is simple to solve.

1) Find the reference angle

2) Lable the sides

3) Find the ratio (SOH CAH TOA)

4) Plug into the equation

5) Solve!

An example we did during the lesson that shows this process:
