Answer:
Mean=12.5
Median=13
Step-by-step explanation:
What you do for the mean is you add all the numbers together to get 75.
You will then divide it by 6 because there are 6 numbers to get 12.5 as your answer.
The median all you do is find the middle number. The middle numbers are 12 and 14. You will take 12 and 14 and add them together to get 26.
You will then divide it by 2 to get 13 as your answer.

Step-by-step explanation:
Please let me know if you want me to write an explanation for my answer :)
The mass of b equals the mass of d so
24(10-x)=6(x+15)
240-24x=6x+90
30x=150
x=5
mass of d is 6(5+15)=6*20=120
mass of c=180-mas of d=180-120=60°
