Question 1114382
<br>
Although you don't define the variables, it seems obvious from the statement of the problem that x and y are the two segments of the hypotenuse c, and h is the altitude to side c.<br>
x = 144 = 12^2; y = 25 = 5^2; so h is 12*5 = 60.<br>
So the original triangle and both of the small triangles formed by the altitude are scale models of a 5-12-13 right triangle.<br>
That makes a and b 65 and 156; from the given description of the problem, we don't know which is which....
