--assuming I drew it the right way right over here--we could say the measure of angle XYZ--sometimes they'll say "angle XYZ is equal to" but this is a little bit more formal-- the measure of angle XYZ is equal to 77--and what we do is we call each of these little sections "degrees"-- so it's equal to 77--sometimes it's written like that, the same way you would write degrees for a temperature outside-- so you could write 77 degrees like that or you could actually write out the word right over there.
