M1= (x+42)° and m/2=3xº.

angle 1= 54

angle 2= 36

Step-by-step explanation:

We know that's a right angle because it has a square in the corner instead of a circle, so the overall measure is 90.

we can set up the equation like this: m1+m2=90

(x+42)+3x=90

calculate it and you'll get x

x=12

put 12 into the angle equations

1: 12+42=54

2: 3(12)=36
