Answer:

  sin(M) = √7/4

  cos(M) = 3/4

  tan(M) = √7/3

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationships of interest.

  Sin = Opposite/Hypotenuse

  sin(M) = (2√7)/8 = √7/4

  Cos = Adjacent/Hypotenuse

  cos(M) = 6/8 = 3/4

  Tan = Opposite/Adjacent

  tan(M) = (2√7)/6 = √7/3
