Question

An angle measures 37*. What is the measure of its supplement?

Answer 1

143 degrees

Explanation:

180 - 37 = 143

Answer 2

143°

Explanation:

supplementary angles are angles that combine to form a straight line (and we know that a straight line = 180 degrees)

you can think of an angle as needing another angle to "supplement" it into being a full line.

So, we know that one angle = 37°

And that: one angle + supplementary angle = 180 degrees

37° + x = 180°

- 37 -37

x = 143

So, the measure of this angle's supplement is 143°

hope this helps!!
