How do you find a missing angle of a triangle using sine cosine and tangent

There is a math trick my teacher taught me called SOH CAH TOA.

That is an acronym for Sin, Opposite over Hypotenuse. Cosine, Adjacent over Hypotenuse, Tan, Opposite over Adjacent.

Sin: To find Sin, you divide the opposite side of the missing angle by the Hypotenuse.

Repeat the process for the other two.
