To determine the values of M and N in the given right triangle we need first to determine the value of angle P. Angle P is equal to the supplementary angle of the 152° angle, that is:
Solving for angle z:
To determine the value of N we can use the function sine since this function is defined as:
REplacing the known values:
Solving for N by multiplying both sides by 9:
Solving the operation:
To determine the value of M we can use the function cosine since this function is defined as:
Replacing the known values:
Multiplying both sides by 9:
Solving the operation:
