Why do you repeat everything twice? Very annoying.
not very many steps involved.
The first step is to know what "supplementary" means -- the measures of the two angles add up to 180°
Now, since you have expressions for those measures, just add 'em up:
4y+7 + 9y+4 = 180
13y = 169
y = 13
So, m∠2 = 9*13+4 = 121°
∠ 1 and ∠ 2 ∠1 and ∠2 are supplementary angles. m ∠ 1 is 4 y + 7 , and m ∠ 2 is 9 y + 4 m∠1 is 4y+7, and m∠2 is 9y+4. Find m ∠ 2
can somebody please explain everything to me, step by step, because i don't understand how to get to some steps
