And this one is hard to solve too that i am having trouble

STEP 1:
Find inner angle by 123°. Let's call the inner angle x. Lines equal 180° so x plus 123° equal 180°.

x + 123°= 180
subtract 123 from both sides
x= 57°

STEP 2:
Triangles equal 180°. Add known angles and subtract from 180 to find angle y.

56° + 57° + y= 180°
113 + y= 180
subtract 113 from both sides
y= 67°

ANSWER: y=67°

Hope this helps! :)

Iwould say that is c
