PLEASE HELP !! ASAP !

Answer 1

Answer:

Step-by-step explanation:

a). Equation: m∠K + 40° + 60° = 180°

    [Since, these angles are located at a point of a straight line so they are   supplementary angles]

b). m∠K = 180° - 100°

    m∠K = 80°

c). Equation: m∠M + m∠K = 180°

   [Since, ∠M and ∠K are the supplementary angles]

d). m∠M + 80° = 180°

    m∠M = 180 - 80

              = 100°
