Gail and her 3 friends all share half a pie. All the pieces in thwe pie put together make up 180 degrees. Gail and her friends finish the pie and they each eat an equal piece. They believe each piece has an angle equal to 25 degrees. are their calculations correct? Explain.

No, should be 60

jhuh

No, they are incorrect because the answer is 45. =)

To determine whether their calculations are correct, we need to analyze the information given and perform some calculations:

1. Gail and her 3 friends share half a pie. Since the total angle of the pie is 180 degrees, each half of the pie will have 90 degrees (180 degrees divided by 2).

2. Gail and her friends finish the pie, meaning that they consume the entire 180 degrees of the pie.

3. They believe each piece has an angle equal to 25 degrees.

Now, let's calculate the angle of each piece to verify their calculations:

Since there are four people (Gail and her three friends) who equally share the entire pie, and we know that the total angle is 180 degrees, we divide 180 by 4:

180 degrees ÷ 4 = 45 degrees

Therefore, each person's equal share of the pie is 45 degrees, not 25 degrees as they believed.

In conclusion, their calculations are incorrect. Each piece would have an angle of 45 degrees, not 25 degrees.
