Answer:
x=7
y=8
Step-by-step explanation:
-Given that the mean and median is the same.
-Let b=mean =median
#Given that the set is arranged in order and is even:

Hence:

-Applying the mean formula:

#Since the number are in order:

Hence, x=7 and y=8
The perimeter is the measure around the shape, so just add all the sides together-
6+5x+x+2
6x+8
Since this is a right triangle, you multiply the legs (6 and x+2) and divide by 2
6(x+2)
6x+12
/2
3x+6
Step-by-step explanation:
