Question

aob is a straight line and the ray oc lies on it. if angle AoC=4x and angle boc =5x find the angles?​

Answer 1

Answer:

Step-by-step explanation:

hey mate answer is 35 as the 180- AOC.(145)= 35° because of angle AOC and angle boc is a linear pair hope this helps you please mark as brainist answer

Answer 2

Answer:

∠AOC = 80° and ∠BOC = 100°

Step-by-step explanation:

Let a be the angle AOC and b be the angle BOC.

Then,

a = 4x and b = 5x

According to linear pair concept,

a + b = 180°

=> 4x + 5x = 180°

=> 9x = 180°

=> x = 20°

Then,

a = 4x = 4 × 20° = 80°

b = 5x = 5 × 20° = 100°
