Answer:
x = 20
Step-by-step explanation:
You can use Pythagorean theorem which is 
a = 12
b = 16

144 + 256 = c^2
400 = c^2
square root
c = 20 or x = 20

If M is the midpoint of segment RS, then
M = (R + S)/2
2M = R + S . . . . . multiply by 2
S = 2M - R = 2(8, -2) -(10, 5) = (6, -9) . . . . put in the given values
