Solve for X and y using both equations the point you get will be the point they cross eachother -x-y=1 y=x+3 -x-(x+3)=1 -x-x-3=1 -2x-3=1 +3 both sides -2x=4 ÷-2 both sides x=-2 solve for y y=-2+3 y=1 (-2,1)
to find J, subtract 122 from 180, you get 58. The total number of degrees is 180. Since L is given as 67, and 67+58=125. Simply subtract 125 from 180 which is 55 degrees
