If two angles are vertical angles (meaning they are across from each other at an intersection of two lines), then they must be congruent, meaning they have the same measure. Therefore, angle 1 will have a measure of 63 degrees also. If you have more questions about why this is, let me know in the comments and I can explain more, or we can schedule a session to discuss in more detail if you have other questions as well.

Vertical angles are equal because they are supplementary to the same angle.
