8,-4 : 6,-2 : 5,-1 All should add up to four.
Hi there! :)

Find the central angle using a ratio in regards to angle and circumference.
The radius is 27 units, so use the following equation to calculate circumference:
C = 2rπ
Therefore:
C = 2(27)π = 54π
Since we have the total circumference, we can write the following proportion:

Cross multiply:
54πx = 6480π
Divide both sides by 54π to isolate for x:
x = 120°
Answer
Find out the do they have enough tickets altogether for a prize that is worth 100 tickets .
To prove
For each balloon game you win at the fair, you get 5 tickets.
Jamal won 9 balloons games.
Thus
Total number of tickets Jamal have = 9 × 5
= 45 ticket
Gary won 6 balloon games.
Total number of tickets Jamal have = 6 × 5
= 30 ticket
Total number of ticket Jamal and Gary have = 45 + 30
= 75 tickets
No, they do not have enough tickets altogether for a prize that is worth 100 tickets .
