Because triangle AMS and triangle ENR are congrugent, so we have:
-> angle SAM = angle NER
-> 112° = 16x°
-> x = 7
and bc the two triangle are congrugent so we also have:
SM = NR = 41
if you need to solve for x and y, just set the two equation like this:
41 = 3x + 5y
plug x = 7 in:
-> 41 = 3.7 + 5y
-> y = 4
I hope this will help!
