Question

in adjoining figure segment ab is diameter of circle m(arc AKC ) =40 find the value of angle ABC ?​

Answer 1

Answer:

140°

Step-by-step explanation:

Seg AB is a diameter

⇒ M (arc ACB) =180° [Angle Made in Semi circle = 180°]

⇒ M (arc AKC) +m (arc BMC) = m (arc ACB) [Arc Addition

Property]

⇒ 40+ m (arc BMC) = 180°

⇒ M (arc BMC) = 180° -40°

⇒ M (arc BMC) =140°
