Find two supplementary angels such that the measure of the first angle is 38° less than three times the measure of the second

Sagot :


angle 1+ angle 2=180    supplementary angles add up to 180

angle 2=x     assign angle a variable

angle 1= 3x-38      find equation for first angle

3x+x-38=180      set both angles added together equal to 180

4x-38=180        combine like terms

4x=218        add 38 to both sides

x=54.5        divide by 4

angle 2= 54.5

angle 2= (3x54.5)-38   plug back in and solve

angle 1= 125.5
