Question

Please help I need it done tonight and I’m lost

Answer 1

1. 88°

2. 90°

3. 190°

4. 170°

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°
