1.) 72 degrees
one straight line=180 degrees
so
2x+3x=180
5x=180
x=36
then since you need angle of ABC, if you look, ABC is 2x and we solved that x is 36 so 2x=2(36)=72
2.) 52 degrees
honestly this is a trick question but if you look closely, angle EFG is in a 90 degree angle with GFH. So literally all you have to do is 90-38= 52
