Answer:

  sin(Z) = 3/5

  cos(Z) = 4/5

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you how to do this.

  Sin = Opposite/Hypotenuse

  sin(Z) = XY/XZ = 9/15

  sin(Z) = 3/5 . . . . . reduced fraction

__

  Cos = Adjacent/Hypotenuse

  cos(Z) = YZ/XZ = 12/15

  cos(Z) = 4/5 . . . . . reduced fraction
