Answer 2

The measure of
`m \angle b` is
`79^\circ`.

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

`m \angle a=79^\circ` (Vertically opposite angles)

Now,
`m \angle a` and
`m \angle b` forms the corresponding angle pair, thus they are congruent.

Hence,
`m \angle a=m \angle b=79^\circ`.

Therefore, the measure of
`m \angle b` is
`79^\circ`.
