The mean is the average value of the numbers given in the series
The mode is the number that is appears more than any other number given in the series
Step-by-step explanation:
Given challenge is make a list of 5 numbers
The list of 5 number is = 8,10,12,15,15

so required mean is 12 has been computed
Mode = 15 ( the number 12 is appeared in two times 8,10,12,15,15)
Final answer
The required numbers are = 8,10,12,15,15

Answer:
The measures of the angles at its corners are 
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the measure of angle A
Applying the law of cosines


![cos(A)= [215^{2}+125^{2}-185^{2}]/(2(215)(125))](https://tex.z-dn.net/?f=cos%28A%29%3D%20%5B215%5E%7B2%7D%2B125%5E%7B2%7D-185%5E%7B2%7D%5D%2F%282%28215%29%28125%29%29)


step 2
Find the measure of angle B
Applying the law of cosines


![cos(B)= [215^{2}+185^{2}-125^{2}]/(2(215)(185))](https://tex.z-dn.net/?f=cos%28B%29%3D%20%5B215%5E%7B2%7D%2B185%5E%7B2%7D-125%5E%7B2%7D%5D%2F%282%28215%29%28185%29%29)


step 3
Find the measure of angle C
Applying the law of cosines


![cos(C)= [125^{2}+185^{2}-215^{2}]/(2(125)(185))](https://tex.z-dn.net/?f=cos%28C%29%3D%20%5B125%5E%7B2%7D%2B185%5E%7B2%7D-215%5E%7B2%7D%5D%2F%282%28125%29%28185%29%29)


How you would solve this problem is:
60 divided by 5 = 12
So there will be 12 toppings.
4
4 - 3 = 1
1 - 3 = -2
-2 - 3 = -5
-5 - 3 = -8
It's the arithmetic sequence.
