Question 1049252: given <1=2x+y, <2=x+30, <3=3y+20. If <1 is supplementary to <2 and <2 is supplementary to <3, what is the measure of <3 Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! I'll use A, B, and C instead of 1, 2, and 3 to make it more readable.
So then,
Substituting,
1.
and
2.
Multiply eq. 2 by 3 and subtract from eq. 1,
and
So then,
