Explanation:
For this exercise you need to analize the information given.
You know that the measure of the angle
is:
![m\angle AOB=110\°](https://img.qammunity.org/2020/formulas/mathematics/middle-school/1g65c1ewl3t4mviv5cnavmdu3810add5z4.png)
This means that:
![\angle1+\angle2+\angle3=110\°](https://img.qammunity.org/2020/formulas/mathematics/middle-school/3brhaefxxcvhsa8gucn5ehbtjvg28s9hr6.png)
Knowing that:
![\angle 1=2x\\\angle\ 2=x+10\\\angle 3=x](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ykzz8jh40tuid7n6t7pycmlyp6z8k0rqua.png)
You can substitute values into the equation:
![2x+x+10+x=110](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4rq5bj8qigis3e9v4bzc538be2hwwvpa9a.png)
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](https://img.qammunity.org/2020/formulas/mathematics/middle-school/8dz540zzag8gawc691px6clu0q53fsrk48.png)
