Answer:
y=100
x=9
Step-by-step explanation:
I'm not positive but x=9.
5x+10=55 subtract 10 from both sides
5x=45 then divide by 5
x=9
angles M and K should be congruent so Y should =100 also.
heres where I'm unsure:
with x being 9 the (x+10)° would be 19 meaning angle L would also be 19. which I don't think is right.
