Question

Given that <3 is a supplement of <4 and that m<3=117 degrees, find m<4.

Answer 1

supplementary angles are two angles that add up to 180 degrees.
so....<3 + <4 = 180
<3 is 117
so sub in 117 for <3
117 + <4 = 180
<4 = 180 - 117
<4 = 63 degrees

So if they're supp. they add up to 180? Thank you so much!!
