Answer:
x=25

Explanation:

For this exercise you need to analize the information given.

You know that the measure of the angle
\angle AOB is:


m\angle AOB=110\°

This means that:


\angle1+\angle2+\angle3=110\°

Knowing that:


\angle 1=2x\\\angle\ 2=x+10\\\angle 3=x

You can substitute values into the equation:


2x+x+10+x=110

Having this, you need to solve for the variable "x" in order to find its value. This is:


4x+10=110\\\\4x=110-10\\\\4x=100\\\\x=(100)/(4)\\\\x=25
