EXERCISES FOR RIGHT-TRIANGLE ANALYSIS Task 1: Consider the right triangle on the previous page and calculate the unknown for each prob- lem in the ser. Make sure the calculations are near. Drawings should be included as well. Keep your work as you will combine it with the theoretical calculations below: 1. X = 20 units, Y = 10 units, 0 = 2. Y - 10 units, r = 15 units. of B 3. X = 20 units, r = 30 units, a = B- 4. X = 8 units, ( = 40". Y = B = A special case would be if x = y, and thus or = B. This is called an isosceles right triangle. You will encounter many of those as you move through general physics
