Unit 8 Homework #4

For the triangle PQR, find the trigonometric ratios.

• - sin Q = 7/25

  - sin R = 24/25

  - cos Q = 24/25

  - cos R = 7/25

  - tan Q = 7/24

  - tan R = 24/7

• - sin Q = 7/25

  - sin R = 7/25

  - cos Q = 27/25

  - cos R = 7/25

  - tan Q = 7/24

  - tan R = 24/7

• - sin Q = 7/24

  - sin R = 24/25

  - cos Q = 7/25

  - cos R = 7/25

  - tan Q = 7/24

  - tan R = 24/7

• - sin Q = 24/25

  - sin R = 7/25

  - cos Q = 24/25

  - cos R = 7/25

  - tan Q = 7/24

  - tan R = 24/7
