Question

Parallel lines: Solve for Y

Answer 1

Explanation:

Well, we know that when we have parallel lines, by the alternating interior angle theorem, we know that alternate angles are congruent.

So, 2y = 70 makes y = 35.

Answer 2

35

Explanation:

Since they are the same angle in the corresponding parallel line, they will equal eachother.

2y = 70
