Question 1014055
.
My teacher had a question on my qiuz today that had a triangle with only one side. That side was the hypotenuse and the value was 25. 
The question was to find the missing sides. Round to the nearest ten. Can you please explain to me how to find this answer.

<pre>
1. First solution is  {3, 4, 5}:  {{{3^2 + 4^2}}} = {{{5^2}}} as everybody knows.

2. The second solution is to take one leg of an arbitrary length less then 5:
   any  x,  0 < x < 5.
   Then calculate  y = {{{sqrt(5^2 - x^2)}}}.
   It will be the second leg.
