You have an isosceles triangle, that is, you have a triangle with two equal angles and two equal sides.

Then, angles N and M have the same measure.

In order to find the measure of angle M, you first equal the given expressions for such angles:

2x = x + 30

solve the previous equation:

2x = x + 30 subtract x bot sides

2x - x = 30 simplify like terms

x = 30

next, replace the previous value of x into the expression for angle M:

x + 30 = 30 + 30 = 60

Hence, the measure of angle M is 60°
