Explanation:
You can identify from the given figure that the angle that measures 70 degrees is formed by two intersecting Chords.
It is important to remembe that, by definition:
![Angle\ Formed\ by\ Two\ Chords =(1)/(2)(Sum\ of\ Intercepted\ Arcs)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ed8wt7sv0q49mz3j671lzkid84uszy25i2.png)
Based on this, you know that:
![70\°=(35\°+x)/(2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mewuev9kfbdpxx7a85mdmbdh5m7ilu7iyh.png)
Having this equation, the final step is to solve for "x" in order to find its value. You get that this is:
![(70\°)(2)=35\°+x\\\\140\°=35\°+x\\\\140\°-35\°=x\\\\x=105\°](https://img.qammunity.org/2020/formulas/mathematics/middle-school/q5spoi0un6xodw93693x49jhm9z8brr9kb.png)
