*Learning Goal: Build proficiency with finding missing sides in right triangles using trigonometry.*

# Classwork

# Standards:

**Common Core**- HSG.SRT.C.7 – Explain and use the relationship between the sine and cosine of complementary angles.
- HSG.SRT.C.8 – Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.

**TEKS**- G.9(A) – determine the lengths of sides and measures of angles in a right triangle by applying the trigonometric ratios sine, cosine, and tangent to solve problems
