As given by the question

There are given that the measuring circle.

Now,

From the given circle, the length of the MN is 28 units, because the half of the length of the MN is 14. So just multiply by 2 into half of the given value.

Hence, the length of MN is 28 units.

Now,

For the measure of MN:

The measurement of the angle MN is 74 degrees.

Hence, a measure of arc MN is 74 degrees. and the length of segment MN is 28 units.
