Answer:
1. 88°
2. 90°
3. 190°
4. 170°
Step-by-step explanation:
The measure of an inscribed angle is half the measure of the intercepting arc (the intercepting arc would be the arc I highlighted red in the image).
Using that information,
1. 68 + 108 = 176. 176/2 = 88. m<E = 88°
2. Arc DB = 180° (semicircle). 180/2 = 90°
3. 95 * 2 = 190°
4. 85 * 2 = 170°
