In the figure AOB is a straight line then the value of x is Option 1: 60 Option 2: 50 Option 3: 40 Option 4: 70

Answer: 40. Solution: Since AOB is a straight line, angles on one side sum to 180: (2x-10) + (x+10) + (x+20) = 180. Simplifying: 4x + 20 = 180, so 4x = 160 and x = 40.

In the figure AOB is a straight line then the value of x is

✅ Correct Option: 3

Since AOB is a straight line, angles on one side sum to 180 $\degree$ : $(2x-10) + (x+10) + (x+20) = 180$ . Simplifying: $4x + 20 = 180$ , so $4x = 160$ and $x = 40$ .
