Answer 1

Since the cake was cut into 12 equal slices, each slice represents an angle of 360°/12 = 30°.

If 8 slices were eaten, then the angle measure of the cake that was left is 12 - 8 = 4 slices.

4 slices * 30° = 120°

Therefore, the angle measure of the cake that was left is 120°.

So the answer is 120°.
