suppose there is a triangle ABC
and A and C are complementary
suppose A=30 so,B=60
we know that, A+B+C =180
30+60+C=180
C=180-90
C=90
and A and C are complementary

30+60+C=180
C=180-90
C=90

We have angle A and B =90
So, (A+B) +C=180
C=180-90 ( because A+B=90)
C=90
So, (A+B) +C=180
C=180-90 ( because A+B=90)
C=90
