Mathematics
1 answer:
crimeas [40]3 years ago
8 0

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°

Liono4ka [1.6K]

Answer:

<u>3.5 meters</u>

Step-by-step explanation:

1 meter = 100 centimeters

multiply both sides by 3.5 because we are trying to get 350 cm in meters.

1 x 3.5 meters = 100 x 3.5 centimeters

<u>3.5 meters </u>= 350 centimeters
