Question 753327: Is there a formula that can figure the lengths of the two legs of a right triangle given only the length of the hypotenuse and a ratio between leg a and b? such as:
'with length c (hypotenuse)=5 and the ratio between legs a and b being 4/3, figure the lengths of a and b' which, obviously in this case, is = to 3 and 4. But what about more complicated ones? like... say if the hypotenuse was 17 and the ratio between a and b is 2.5? Is it completely just trial and error, or is there a formula/expression to at least approximate the lengths to a couple of decimal places?
