Answer:
m<M = 98 deg
Step-by-step explanation:
Theorem
The sum of the measures of the angles of a triangle is 180 degrees.
Now we set the sum of the measures of the angles equal to 180 and solve for x.
3x - 16 + x + 6 + x = 180
5x - 10 = 180
5x = 190
x = 38
Now that we know x, we substitute x with 38 in the expression for the measure of angle M.
m<M = 3x - 16
m<M = 3(38) - 16
m<M = 114 - 16
m<M = 98
