how do i find the degree of a right angle, split into two different angles.
ex. if m<10 = 80*, then m<11 = ?

The two angles must add to 90 degrees
so if one of them is 10
then the other one is 90  10
or 80
If one is 40
then the other is 90  40
or 50
Angles that add to a right angle are called complementary.
