Question 800809
x = measure of the angle
180 - x = measure of supplement {supplementary angles add up to 180°}


x = 74(180 - x) {measure of the angle is 174 times the supplement}
x = 13,320 - 74x {used distributive property}
75x = 13,320 {added 74x to each side}
x = 177.6 {divided each side by 177.6}


the angle is 177.6°
the supplement is 2.4°
