how many degrees in a straight line? Half way around the circle?

Supplementary means that the two angles equal 180 degrees

1 + 2 = 180 <--- this means supplimentary

a) 180 degrees b) 180 degrees c) is true d) angle 3 e) angle 3

the question itself is not that hard, its just that they worded it much more complicated than it needs to be. took me a while to read it

OpenStudy (experimentx):

1 + 2 = 180 === this means ==> 1 = 180 - 2 2+3 = 18 === this means ==> 2 = 180 - 2 180 - 2 = 180 - 2
