Question

Find the pairs of complementary angles from the following pairs.
(i)35°,45° (ii)60°,20°

Answer 1

Answer :

We know sum of complementary angles is 90$°$

So,

i ) x + 35$°$ = 90$°$

x = 55$°$
And

x + 45$°$ = 90$°$

x = 45$°$

So,

Complementary angles for pair = 55$°$ , 45$°$

ii ) x + 60$°$ = 90$°$

x = 30$°$
And

x + 20$°$ = 90$°$

x = 70$°$

So,

Complementary angles for pair = 30$°$ , 70$°$
