Step-by-step explanation:

→You can use the Pythagorean Theorem to solve this, by plugging in the numbers, like so:

→Subtract from both sides:

→Subtract 12x from both sides:

→Factor out x:

→Separate, set = to 0, and solve:

       →      Add 12 to both sides:        

→So we have 0 and 12, as our answers. However, we cannot have 0 as a side length, since this would not be possible.

→All we need to do is take 12, and plug it into the equation for the shortest leg.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

x = 23.78
