## Chapter 7, Lesson 11

**7-11.A** identify trigonometric ratios in right triangles**Refer to ∆ ABC and match each ratio in Column I with all of the appropriate trigonometric ratios shown in Column II. In some cases, more than one match is possible.**

**7-11.B** use trigonometric ratios to find side lengths in right triangles**In right triangle JKL, which equation cannot be used to find the length of LK? **

**7-11. C** use trigonometric ratios to find angle measures in right triangles

**In each right triangle, find the measure of angle X to the nearest degree.**
