Use Pythagoras (x^2 + y^2 = r^2)
Simplified: leg squared plus leg squared equals hypotenuse squared.
Therefore 4^2 + 6^2 = h^2
16+36=h^2
h^2 = 52
H= root of 52=7,21 inches
1/x(x-2) + 1/x = 5/x(x-2)
Let's clear the fractions by multiplying both sides by x(x-2)
1 + (x-2) = 5
x = 6
Check
1/(6(6-2))+1/6 = 5/24
5/(x(x-2)) =5/(6(4))= 5/24, good
Answer: x=6
