Answer:
8x + 22
Step-by-step explanation:
1) Either or ∦ (only two possibilities)
2) Assume (one of two possibilities)
3) (if two parallel lines are cut by a transversal, the corresponding angles are congruent)
4) But is not congruent to (given)
5) So ∦ (only other possibility)
y = -17/2
Substitute with the givens.
30= 8(8) + 4y.
Multiply parentheses.
30 = 64 + 4y
Subtract.
30-64= -34
-34 = 4y.
Divide each side by 4.
y = - 8.5, or -17/2
hope that is right!
