  1. Finding the measure of an acute angle of a right triangle given two side lengths

  2. STEPS: • 1) Label the unknown angle with an arc, and the sides with O,A and H. • 2) Set up a trigonometric ratio equation using the two unknown sides. • 3) Solve for the unknown angle. • 4) Make a conclusion if you are solving a real-world problem

  3. Example 1: • J Determine J. • K 43cm • L

  4. Example 2: • A Find <C: • 45m • 40m • C • B

  5. Example 3: • Casper is 15m away from the wall of a building. If the height of the building is 10m, determine the angle of depression from the top of the building to Casper.
