to solve the leg of a right triangles given the two other side, use the pythagorean theorem. which state that
C^2 = a^2 + b^2
where C is the hypotenuse of the right triangle
a and b are the legs of the right triangle
since the unknown is the other leg
b^2 = C^2 - a^2
b^2 = 18^2 - 14^2
b^2 = 128
b = 11.3 cm
