- For the triangle with hypotenuse 10 and adjacent side 8:
- sinθ = 6/10 = 3/5
- cosθ = 8/10 = 4/5
- tanθ = 6/8 = 3/4
- cscθ = 10/6 = 5/3
- secθ = 10/8 = 5/4
- cotθ = 8/6 = 4/3
- For the triangle with hypotenuse 15 and opposite side 9:
- sinθ = 9/15 = 3/5
- cosθ = 12/15 = 4/5
- tanθ = 9/12 = 3/4
- cscθ = 15/9 = 5/3
- secθ = 15/12 = 5/4
- cotθ = 12/9 = 4/3
- For the triangle with hypotenuse 25 and opposite side 20:
- sinθ = 20/25 = 4/5
- cosθ = 15/25 = 3/5
- tanθ = 20/15 = 4/3
- cscθ = 25/20 = 5/4
- secθ = 25/15 = 5/3
- cotθ = 15/20 = 3/4
- For the triangle with opposite side 5 and adjacent side 12:
- sinθ = 5/13
- cosθ = 12/13
- tanθ = 5/12
- cscθ = 13/5
- secθ = 13/12
- cotθ = 12/5
- For the triangle with hypotenuse 39 and adjacent side 24:
- sinθ = 15/39 = 5/13
- cosθ = 24/39 = 8/13
- tanθ = 15/24 = 5/8
- cscθ = 39/15 = 13/5
- secθ = 39/24 = 13/8
- cotθ = 24/15 = 8/5
