Answer:
x= 34° , angle AOC = 122° and angle BOC = 58°
Step-by-step explanation:
angle AOC + angle BOC = 180°
2x -10+3x+20 = 180°
5x+10=180°
5x= 180-10= 170°
x= 170/5= 34°
1. Angle AOC= 3x+20
= 3(34)+20
= 102+20
Angle AOC = 122°
2. Angle BOC = 2x-10
= 2(34)-10
= 68-10
= 58°
Angle BOC= 58°
Hence Angle AOC = 122° and Angle BOC = 58°
Hope this will help you
