Alright! We now have all 3 of the Trigonometric Ratios needed to tackle Right Triangles that may be so foolish as to get in the way of our pencils and calculators.

Dont forget,

You have to look at the Triangle, figure out what you have, choose an appropriate Ratio based on SOH CAH TOA.

When you have an angle and a side, use TAN to find your unknown triangle side length.

When you know 2 sides, Use 2nd FUNCTION + TAN to find the angle in degrees.

HW today is on p. 120 Q1-3 (ACE), 4-12
