Answer:
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
