  3. 7.7 Solve Right Triangles

  4. To solve a right triangle: • Find the measures of all its sides • Find the measures of all its angles.

  5. You will need to know one of the following: • Two side lengths • One side length and the measure of one acute angle

  6. Inverse Trig Ratios – when you 2 side lengths

  7. Example 1: • Use the calculator to approximate the measure of <Q to the nearest tenth of a degree.

  8. Example 2: Let <C be an acute angle in a right triangle. Use the calculator to approximate the measure of <C to the nearest tenth of a degree. • sin C = 0.24 • cos C = 0.37 • sin C = 0.76 • cos C = 0.17

  9. Example 3: • Solve the right triangle formed by the water slide shown in the figure. Round decimal answers to the nearest tenth.

  10. Example 4: • Solve the right triangle. Round decimal answers to the nearest tenth.

  11. Example 5: • A road rises 10 feet in a horizontal distance of 200 feet. What is the angle of inclination?

  12.  Homework  • Pgs. 485 – 486 (3, 4, 6 – 8, 10 – 18 evens)
