    A^2 + b^2 = c^2 12^2 + 16^2 = c^2 C = 400 so we square that and get the third side which is 20

    I am assuming this is a right traingle

    if a right triangle has legs legnth a and b and hypotonuse legnth c then

    a²+b²=c²

    legs are 12 and 16

    a=12

    b=16

    12²+16²=c²

    144+256=c²

    400=c²

    sqrt both sides

    20=c

    the legnth is 20in, assuming you have a right triangle
