Question

Which angles are supplementary to <3?

A) <1
b) <4
C) <5
D) < 8

Please explain How you got the answer as well, thanks!

Answer 1

Supplementary means that the angles add up to 180 degrees. A linear line also equals 180 degrees. So the answer would be angle 4, as angle 3 and angle 4 make a linear line together, which equals 180 degrees, and adds up to be a supplementary angle.

Answer 2

<4 is supplementary to <3.

Explanation:

Given : Angles.

To find : Which angles are supplementary to <3.

Solution: We have given Different angles,

As we know that

The sum of two linear pair angles is 180 degree.

<3 ,<4 are linear pair angle because it formed at line

<3 + <4 = 180 ( Supplementary)

Therefore, <4 is supplementary to <3.
