Question

What is the relationship between ∠a and ∠b?Choose 1 answer:A. Vertical anglesB. Complementary anglesC. Supplementary anglesD. None of the above

Answer 1

Answer:

C. Supplementary angles

Explanation:

Angles a and b are on the straight line AC.

Recall that the sum of angles on a straight line is 180 degrees.

If two angles add up to 180 degrees, they are said to be Supplementary.

Hence angles a and b are Supplementary angles.
