Answer:
![176\°](https://tex.z-dn.net/?f=176%5C%C2%B0)
Step-by-step explanation:
we know that
The inscribed angle is half that of the arc it comprises.
so
In this problem
Let
x-----> the measure of an arc intercepted by an inscribed angle
![88\°=\frac{1}{2}(x)](https://tex.z-dn.net/?f=88%5C%C2%B0%3D%5Cfrac%7B1%7D%7B2%7D%28x%29)
![x=2(88\°)=176\°](https://tex.z-dn.net/?f=x%3D2%2888%5C%C2%B0%29%3D176%5C%C2%B0)
