Answer:
Z = 53
Y = 74
Step-by-step explanation:
so a triangle, all angles equal up to 180 and also a straight line equals 180
so, 180 - 127 = 53
it is an isosceles triangle so the bottom 2 sides are the same number so angle Z = 53
add 53 and 53 because you need to subtract it from 180 to get y
53 + 53 = 106
the subtract 106 from 180
180 - 106 = 74
so angle y = 74
