Question

How do I write down the size of each angle mark by a letter?

Answer 1

In the given figure, the two lines are parallel as indicated by the arrows.

The angles 37° and m are alternate interior angles.

The alternate interior angles are inside the parallel lines and on alternate sides of the third line.

The alternate interior angles are always equal.

This means that the angle m must be equal to 37°

`m=37\degree`

Therefore, the measure of angle m is 37°
