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

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

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 = 0.4402 Find the measure of <A to the nearest tenth of a degree.

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

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

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.

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