Answer:
138.5°
Step-by-step explanation:
Since the peach pie is a circle, we have a total angle of 360°.
We need to determine what fraction of the total pie of 13 peaches is the 5 peaches contained in Joe's slice.
This is number of peaches in Joe's slice/total number of peaches in pie = 5/13. To find the angle Joe's slice measures, we multiply 5/13 by 360°.
So, 5/13 × 360°
= 0.3846 × 360°
= 138.46°
≅ 138.5° to the nearest tenth of a degree
51/4 is the correct answer
