Question 577630: <1 and <2 are supplementary angles. m<1 is 4y +7 and m <2 is 9y + 4. find m<2
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
m < 1 + m < 2 = 180

4y+7 + 9y+4 = 180

13y+11=180

13y=180-11

13y=169

y=(169)/(13)

y=13

--------------------------

m < 2 = 9y+4

m < 2 = 9(13)+4

m < 2 = 117+4

m < 2 = 121

So the measure of angle 2 is 121 degrees.
