Question

in the given figures , <AOB=120⁰ and <DOC=110⁰. find the measure of the each of the following angles:
i. <AOC
ii.<AOB
iii.<AOD

please solve it is urgent please

with process​

Answer 1

Answer:

∠AOB =120°

⇒ ∠AOC + ∠BOC = 120

⇒ ∠AOC = 120-50

⇒ ∠AOC = 70°

⇒ 2x = 70°

∠AOB = 120° (given )

∠BOD = ∠DOC - ∠BOC

⇒ 3y = 110 - 50

3y = 60°

∴∠AOD = 360 - (60 + 50 + 70)

⇒ ∠AOD = 360 - 180

⇒ ∠AOD = 180°
