What does supplementary mean?

anonymous · Answer

(3x+22) + (5x-2) = 180 
8x+20=180 
8x= 160 
x= 20

im supposeed to find angle Q. how do i know that that is Q?

anonymous · Answer

Alright, if R and Q are supplementary, then the two angels added together equal 180 rigght? look at my work up there and it makes sence

anonymous · Answer

the number 20 can be Q or R, how do I know the answer is 20?

anonymous · Answer

argh, I'm trying to get you to do a little thinking... okay, if x=20, then you know what Q AND R is because all you have to is plug 20 into x. so 5(20) -2 => 100-2 => 99.
Q=99 degrees
