Exercise:

The North Galactic Pole is at Right Ascension 12h49m, declination +27°24'.
What is the tilt of the galactic plane to the celestial equator?

This one is really easy!

The distance from the North Celestial Pole P to the North Galactic Pole G
is just (90°- declination of G) = 62.6°.

So this is also the tilt of the galactic plane to the equator.
