Answer:
Explanation:
To display the results of the rugby team games last year in a pie chart with an angle size of 150 degrees, Michael can follow these steps:
Calculate the percentage of games won, lost, and drawn:
Percentage of games won: (15 / 25) x 100% = 60%
Percentage of games lost: (20 / 25) x 100% = 80%
Percentage of games drawn: (25 - 15 - 20) / 25 x 100% = 20%
Calculate the angle size for each segment of the pie chart:
Angle size for games won: 60% x 150 degrees = 90 degrees
Angle size for games lost: 80% x 150 degrees = 120 degrees
Angle size for games drawn: 20% x 150 degrees = 30 degrees
Draw a circle and mark the center point.
Draw a line from the center point to the edge of the circle. This will be the first segment of the pie chart.
Use a protractor to measure the angle size for the first segment (90 degrees) and mark it off on the edge of the circle.
Repeat steps 4 and 5 for the other two segments (120 degrees and 30 degrees).
Label each segment with the corresponding result (win, lose, draw) and the percentage of games.
The resulting pie chart should have three segments: one for games won (60% of 25 games), one for games lost (80% of 25 games), and one for games drawn (20% of 25 games). The segment for games won should have an angle size of 90 degrees, the segment for games lost should have an angle size of 120 degrees, and the segment for games drawn should have an angle size of 30 degrees.
