Answer:

26.8

Explanation:

We can use the Pythagorean theorem

a^2+b^2 = c^2

where a and b are the legs and c is the hypotenuse

12^2+ b^2 = 18^2

144+b^2 = 324

b^2 = 324-144

b^2 = 180

Taking the square root of each side

sqrt(b^2) = sqrt(180)

b = 13.41640

We know b = 1/2x

2b =x

2(13.41640) =x

26.83281573 =x

26.8
