my math teacher never explains us things that we dont under stand, shes really weird, but my qusetion is how do i find the complement and supplement of a angle measure. like how would i do that for 40 degrees? can you give me an example maybe? cause i really dont get how to do this, she just gave us a peice of paper and told us to do it for homework.

This is easy.
Complementary angles add up to 90.
Supplementary angles add up to 180.
So if two angles are complementary and one is 40, the other is 50.
40 + x = 90
x = 90 - 40
x = 50
If two angles are supplementary and one is 40, the other is 140.
40 + x = 180
x = 180 - 40
x = 140
If an angle has a measure of 'x':
The complementary angle is 90 - x
The supplementary angle is 180 - x
Does that make sense? If not I can try to explain it another way...

Supplementary angles add up to 180° and complementary angles add up to 90°.
Let's look at a 40° angle:
Since supplementary angles add up to 180°, to find the supplement of 40°, you would subtract 40° from 180° (180 - 40):
180° - 40° = 140°
Since complementary angles add up to 90°, to find the complement of 40°, you would subtract 40° from 90° (90 - 40).
90° - 40° = 50°
*** The supplement of 40° is 140°, and the complement is 50°.

Complementary angles add to 90.
So the complement angle of 37 degrees is 53 degrees
Supplementary angles add to 180
So the supplement angle of 37 degrees is 143

The complement of an angle is 90° minus the angle (in your example, 50°). The supplement of an angle is 180° minus the angle (in your example, 140°).

Two angles are called supplementary angles if the sum of their degree measurements equals 180 degrees. One of the supplementary angles is said to be the supplement of the other.
Two angles are called complementary angles if the sum of their degree measurements equals 90 degrees. One of the complementary angles is said to be the complement of the other.

complement angle is 90 degree and supplement is 180 degree.
it is problability gonna be subtracting from 90 or 180 to find the angle you need

okay... for comp. u wud subtract the # frm 90 : 90- 40 which is 50 as ur complement and for supp u wud subtract it frm 180 : 180 - 40 which is 140 as ur supplement
hope this helped!!!
