**8.3 Solving Right Triangles**

2
Examples: Use the trigonometric ratio to determine which angle of the triangle is A.

3
Examples: Use the given trigonometric ratio to determine which angle of the triangle is A.

4
Examples: Use the given trigonometric ratio to determine which angle of the triangle is A. tan A = 1.875

5
**Solving Right Triangles:**

If you know the sine, cosine, or tangent of an acute angle measure, you can use the inverse trigonometric functions to find the measure of the angle.

6
Examples: Use your calculator to find each angle measure to the nearest degree. cos-1(0.87) sin-1(0.85) tan-1(0.71) tan-1(0.75) cos-1(0.05) sin-1(0.67)

7
**Solving Right Triangles:**

Solving a triangle: finding all unknown side lengths and angle measures.

8
Examples Find the unknown measures. Round lengths to the nearest hundredth and angle measures to the nearest degree.

9
Examples Find the unknown measures. Round lengths to the nearest hundredth and angle measures to the nearest degree.

10
Examples: The coordinates of the vertices of ∆PQR are P(–3, 3), Q(2, 3), and R(–3, –4). Find the side lengths to the nearest hundredth and the angle measures to the nearest degree.
