Question

Which of the following pairs of angles is not a pair of complementary angles? *

1 point

(a) 60°, 30°

(b) 66°, 34°

(c) 0°, 90°

(d) 160°, 30°

Answer 1

Note : Sum of complementary angles is always 90°

By checking all options

$\boxed{ \sf 60 + 30 = 90} \\ \sf 66 + 34 = 100 \\ \boxed{\sf 0 + 90 = 90 }\\ \sf \: 160 + 30 = 190$

➡️ From above we can conclude that option (a) and (c) are the pairs of complementary angles

Therefore,

Option (b) and (d) are the answers since they are not the pairs of complementary angles
