angle 1+ angle 2=180    supplementary angles add up to 180angle 2=x     assign angle a variableangle 1= 3x-38      find equation for first angle3x+x-38=180      set both angles added together equal to 1804x-38=180        combine like terms4x=218        add 38 to both sidesx=54.5        divide by 4angle 2= 54.5angle 2= (3x54.5)-38   plug back in and solveangle 1= 125.5
