  2. Vocabulary • To solve a right triangle means to find the measures of all of its sides and angles.

  3. Inverse Trigonometric Ratios: • You can use the inverse of the ratio to find the missing angle measure.

  4. Example 1: • Find the measure of X. Round to the nearest tenth.

  5. Example 2: • Approximate the measures of A and B to the nearest tenth of a degree.

  6. Example 3: • Find the missing measurements of the right triangle shown in the diagram. Round decimal answers to the nearest tenth.

  7. EXAMPLE 4 You Try: Suppose your school is building a raked stage. The stage will be 30 feet long from front to back, with a total rise of 2 feet. A rake (angle of elevation) of 5o or less is generally preferred for the safety and comfort of the actors. Is the raked stage you are building within the range suggested?

  8. You Try: • Solve the triangle
