    The answer should be 20 because you sue the formula a^2 + b^2 = C^2

    so you input 12^2 + 16^2=x^2

    144 + 256 = x^2

    400=x^2

    20

    So Pythagorean Theorem is a^2+b^2=c^2

    So, 12^2+16^2 = 400

    c=400, but you need to find c^2. so do the square root of 400, which is 20. so x=20
