This week, we learned the equations we need to determine the missing side length or degree using trigonometry.

Finding Missing Side Length:

After properly naming your sides, you are able to see if the equation will be a SIN, COS or TAN equation. You are able to determine this using the abbreviation SOH CAH TOA. Then you would solve the equation step by step.

Finding Missing Angle:

When finding the missing angle you are still able to use SOH CAH TOA, but you use the signs to the negative exponent in these equations to determine the missing angle. Then you solve the equation step by step.
