Gail and 3 friends all share 1/2 a pie. All the pieces in pie put together make up 180 degrees. Gail and friends finish the pie and each eat an equal piece. They believe each piece has an angle of 25 degrees. Are they right?
No.
180 / 4 = ?
No. It's 45°.
To determine whether each piece of the pie has an angle of 25 degrees, we need to analyze the given information and do some calculations.
First, we know that the pie is divided among Gail and her three friends, so there are four equal pieces. Since the pie is divided equally, each piece will have an equal angle.
We are told that all the pieces put together make up 180 degrees. Since there are four pieces, we can divide 180 degrees by 4 to find the measure of each angle:
180 degrees ÷ 4 = 45 degrees
Therefore, each piece of the pie has an angle of 45 degrees, not 25 degrees.
The assumption made by Gail and her friends that each piece has an angle of 25 degrees is incorrect.
