Which shows the correct solution of the equation 1/2a+2/3b=50, when b=30?

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1

Is triangle jkl congruent to triangle rst? if so, what is the scale factor?
