Respuesta :

Angle Y would be 63 degrees.

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..
