Step-by-step explanation:

The measure of is .

Step-by-step explanation:

Given: Lines a and b are parallel to each other.

To find: The measure of the angle b.

Solution: It is given that  Lines a and b are parallel to each other, thus using the parallel lines properties, we have

(Vertically opposite angles)

Now, and forms the corresponding angle pair, thus they are congruent.

Hence, ==.

Therefore, the measure of is .
