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.
