Answer:
The formula for pythagoras is a squared + b squared = c squared. C is the longest side. x isn't the longest side so we rearrange it.
It becomes: c squared - a squared = x squared
c is 24
a is 6
Plug these numbers into the equation:
576 - 36 = x squared
540 = x squared
So, the square root of 540 is 23.2
x is 23.2
