In a right angle there are three different angles one is 34, the other is 22 and we have to find the other angle 'a'. I know that:

a + 34 + 22 = 90

a + 56 = 90

a = 34

However, I am not sure what the reason would be I can't say complementary angles because there are more than two angles. What happens in this case?

Thanks.
