I’m not going to ask for the answer, just in process to solve it.

For this case we have that by definition, the sum of the internal angles of a triangle is 180 degrees.

Then, according to the figure djunta we have:

Grouping similar terms:

We clear the value of x:

Then the angle M is given by:

Substituting the value of x we have:

Thus, the angle M is 98 degrees.

98 degrees
