Question

answer fast I will mark as brainlist answer ​

Answer 1

Step-by-step explanation:

angle AOB =180°

so 2x-10+3x+20 =180

5x+10=180

5x=170

x=34°

angle AOC= 34x2 -10 =68-10 =58

COB= 3x+20 = 122

Answer 2

Answer:

x=34°

<AOC=58°

<BOC=122°

Step-by-step explanation:

2x-10+3x+20 =180(supplementary angles)

5x+10=180

5x=170

x=34°

<AOC= 2x-10= 2(34) - 10 =68-10 =58°

<BOC = 3x+20 = 3(34) +20 = 122°

hope the answer will help you
