Answer:
Given, angle AOC = (2x - 10°) and angle BOC = (3x + 20°) also, AOB is a straight line. The sum of two angles on a straight line is 180° . => x = 34 Answer.
Verified answer
Answer:
36°
Step-by-step explanation:
Here,
(2x-10)+(3x+20)=180
[Because AOB is a straight line angle and straight line angle is 180°]
2x-10+3x+20=180
2x+3x+20-10=180
5x+10=180
5x=170
x=170/5
x=36°
