Objective Use trigonometric ratios to find angle measures in right triangles and to solve real-world problems.

Read lesson and do examples 1 & 2 from your workbook on pages 339 - 340

Example 3: Solving Right Triangles Find the unknown measures. Round lengths to the nearest hundredth and angle measures to the nearest degree.

Example 4: Solving Right Triangles Find the unknown measures. Round lengths to the nearest hundredth and angle measures to the nearest degree.

Example 5: Percent Grade San Francisco, California, is famous for its steep streets. The steepness of a road is often expressed as a percent grade. Filbert Street, the steepest street in San Francisco, has a 31.5% grade. This means the road rises 31.5 ft over a horizontal distance of 100 ft. What is the angle of elevation of the street?

Example 6: Travel Baldwin St. in Dunedin, New Zealand, is the steepest street in the world. It has a grade of 38%. To the nearest degree, what angle does Baldwin St. make with a horizontal line?
