Answer 2

Answer:

103

Step-by-step explanation:

All we have to do is subtract the measure of the line which is 180 by 77 to get the measure of < y. Since they are adjacent to each other this concept will work but if they weren't it would be a little different.

$y+77=180\\y=130$

So the measure of < y is 130°
