6. Example 1: Use Inverse Tangent Use a calculator to approximate the measure of <A to the nearest tenth of a degree.

7. Example 2: Solve a Right Triangle
Find each measure to the nearest tenth. c
m<B
m<A

8. Checkpoint: Use Inverse Tangent <A is an acute angle
Checkpoint: Use Inverse Tangent <A is an acute angle. Use a calculator to approximate the measure of <A to the nearest tenth of a degree. 1) tan A = 3.5 2) tan A = 2 3) tan A = Find the measure of <A to the nearest tenth of a degree.

11. Example 3: Find the Measures of Acute Angles
<A is an acute angle. Use a calculator to approximate the measure of <A to the nearest tenth of a degree.
sin A = 0.55
cos A = 0.48

12. Example 4: Solve a Right Triangle
Solve Triangle GHJ by finding each measure. Round decimals to the nearest tenth.
m<G
m<H g

13. Checkpoint: Use Inverse Sine and Inverse Cosine <A is an acute angle. Use a calculator to approximate the measure of <A to the nearest tenth of a degree.

14. Checkpoint: Use Inverse Sine and Inverse Cosine Solve the right triangle. Round decimals to the nearest tenth.
