Answer 1

Answer:

sorry I didn't understand

Answer 2

Answer:

∠AOC = 150° (Given) By degree measure theorem: ∠ABC = (reflex∠AOC)/2 …(1) We know, ∠AOC + reflex(∠AOC) = 360° [Complex angle] 150° + reflex∠AOC = 360° or reflex ∠AOC = 360° −150° = 210° From (1) => ∠ABC = 210°/2 = 105°Read more on Sarthaks.com - https://www.sarthaks.com/612473/in-figure-it-is-given-that-o-is-the-centre-of-the-circle-and-aoc-150-find-abc
