Answer: y= 50
Step-by-step explanation:
The angles that are formed inside the two lines and on opposite sides of the transversal are known as alternate interior angles.
Consider the given figure , we can see that line b and line c are intersected by a transversal so by the definition of alternate interior angles,
The alternate interior angles formed = [tex]y^{\circ}[/tex] and [tex]50^{\circ}[/tex]
Since we are given that two parallel lines are crossed by a transversal.
Then the alternative interior angles must be congruent.
[tex]\Rightarrow\ y^{\circ}=50^{\circ}[/tex]
Hence, the value of y= 50
