Answer:The Last One
Step-by-step explanation:
First you find the median which is 4. The mean is calculated by the sum of the distribution divided by the amount of numbers in the distribution (20). The mean comes out to be 4.35. Subtract 4.35 from 4 and your answer is .35.
X+x+54=180
2x+54=180
2x=126
x=63
63+54=117
one angle is 63, the other is 117
