Step-by-step explanation:
we know that
if a || b
then
-----> by alternate exterior angles
Solve for x


Find the measure of the labeled angles

1: y=8, (-2,8)
2: y=6, (-1,6)
3: y=0, (2,0)
Step-by-step explanation:
Insert the x value into each equation then see what value of y that you need to get 4 on the right hand side of the equation.
