Find the value of x. then find the measures of angles m and n show your work.

x=32

M=115

N=50

Step-by-step explanation:

Since we know that all the angles of a triangle add up to 180, we can find the value of x by making it an equation.

x+18+4x-13+15=180

Now solve for x.

Add like terms.

5x+20=180

Subtract 20 on both sides.

5x=160

Divide both sides by 5 to isolate x.

x=32.

Now, substitute into 32 for x into the equations to find the measures of the angles.

32+18=50 so the measure of angle n is 50.

4(32)-13

128-13=115 so angle M is 115.

Now we can check the angles.

115+50+15=180?

165+15=180

180=180.

Hope this helps!
