A778
34)

Answer 1

y = 68

Explanation:

For the lines to be parallel, then

78 and 2y - 34 are same- side exterior angles and supplementary, thus

2y - 34 + 78 = 180

2y + 44 = 180 ( subtract 44 from both sides )

2y = 136 ( divide both sides by 2 )

y = 68

Answer 2

The answer would be thirty four
