1. Warm Up (Just give the fraction.) 3. Find the measure of ∠T: ________
4. Solve for the length of AC.
32o 17

2. Def. Trigonometry is the study of the relationships between the angles and sides of a right triangle.
Def. A comparison of the lengths of two sides of a right triangle is called a trigonometric ratio. The three most common ratios of trigonometry are sine, cosine, and tangent.

3. Write this on pg. 698
In a right triangle, the trig ratios can be found by remembering
SOH CAH TOA
