Question

What is the relationship between the pair of angles ABC and LMN shown

in the diagram below?

A. they are supplementary angles
B.they are complementary angles
C.they are adjacent angles
D.they are vertical angles​

Answer 1

Option B.

Explanation:

Measure of ∠ABC = 20°

and measure of ∠NML = 70°

Then ∠ABC + ∠NML = 20 + 70

= 90°

Therefore, ∠ABC and ∠NML are complementary angles because sum of complementary angles is 90°.

Answer 2

the answer is B

Explanation:

the sum of both angles is 90 degree.

By definition if the sum of two angles is 180 is supplementary

If the sum of two angles is 90 is complementary

Then, 70 + 20 =90 degree

So, They are complementary angles
