The measures of the twoa angles in a linear pair are in the ratio 1:3. What is the measure of the lager angle?

asked by Soriano
  1. L = Large angle

    S = Smaller angle


    S = L / 3


    S + L = 180°

    L / 3 + L = 180°

    L / 3 + 3 L / 3 = 180°

    4 L / 3 = 180°

    4 L = 3 ∙ 180° = 540°

    L = 540° / 4 =135°


    S = L / 3 = 135° / 3 = 45°


    Large angle = 135°
