Answer:
y = 123 degree
Step-by-step explanation:
180 - 57-60 = 63
The lines v and t are parallel that v shows us 180-60-57 = 63
The lines t shows us 63 + 60 = 123 degree
The angles can also be solved just 180-57 = 123 but wouldn't prove the comparison of v and t and how mv angle is larger than mh..
