Identify Triangle Angles: Identify the sum of angles in a triangle.In any triangle, the sum of the angles is 180 degrees.
Set Up Equation: Set up the equation.Since angle L is 10x+10 degrees, and the sum of the angles in triangle NML must be 180 degrees, we can write the equation: m+(10x+10)+angle N=180.
Assume Known Angle: Assume angle N is known.We don't have the measure of angle N, so let's assume it's a known value, say 'a' degrees. Now the equation is: m+(10x+10)+a=180.
Solve for m: Solve for m.To find m, we need to subtract the measures of angle L and angle N from 180 degrees. So, m=180−(10x+10)−a.
Missing Values: Realize we don't have values for x or a. We can't solve for m without the values for x or angle N.
