    So, what you’re doing here is basically finding the measurements of a right triangle, so we’ll use the formula

    a^2+b^2=c^2

    now, we plug in what we have

    12^2+x^2= 19^2
    144+x^2= 361

    Bring the variable to one side by subtracting 144 from each side

    x^2= 217

    Square root each side to get rid of the exponent on the x

    x= 14.7309

    ANSWER:
    15 inches
