Question 1016597: Use the linear pairs of angles figure and solve:
http://www.mathwords.com/l/l_assets/l79.gif
if m∠1 = 3x + 7 and m∠2 = 2x - 8
find m∠3
Answer by FrankM(1040) (Show Source): You can put this solution on YOUR website!
m∠1 = 3x + 7 and m∠2 = 2x - 8
m∠1 and m∠2 are supplementary, adding to 180 degrees.
3x+7+2x-8=180
5x-1=180
5x=181
x= 36.2
2(36.2)-8= 64.4 degrees.
angles 3 and 2 are the same.
