To find the mean, u add up all the numbers and divide by how many numbers there are.
the mean : (4 + 8 + 5 + 7 + 6) / 5 = 30/5 = 6
for the median (the middle number)...first, put ur numbers in order...doing this is very important

so both ur mean and ur median are 6 <==
Answer:
x =25
<B = 65 degrees
<C = 50 degrees
Step-by-step explanation:
65 + (3x-10) +2x = 180
Add like terms:
55 +5x = 180
Subtract 55:
5x = 125
Divide by 5:
x = 25
Substitute for x and solve
