Question

In the given figure,AOB is a straight line and the ray OC stand on it.If <AOC=(2x-10)and <BOC=(3x+20),
find the value of x.Also ,find <AOC and <BOC.​

Answer 1

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.

Answer 2

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°
