You need more info
the left side is...(13x+3) and the right side is... (9x+1)
I need to find the larger and smaller angle.
they form a linear pair and so their sum is 180 degree so (13x + 3) + (9x + 1) = 180 22x + 4 = 180 x = 176/22 x = 8

(13x+3)+(9x+1)=180 22x=176 176/22=x x=8 R.S.= 9(8)+1=73 L.S. 13*8+3= 107
so if x=8 just solves both sides and that will give you both angles?
13x + 3 = 13*8 + 3 = 107 degree 9x + 1 = 9*8 + 1 = 73 degree
yes u have to first get value of x......
thanks
