Answer:
D. 68 degrees
Step-by-step explanation:
Remember, the total degree of a triangle is 180 degrees, not 360 like a rectangle.
To solve, set up an equation.
[tex]y+(y-12)+56=180[/tex]
Solve:
[tex]2y+44=180[/tex]
Subtract 44 from both sides
[tex]2y=136[/tex]
Divide both sides by 2
y=68
I hope this helps!
