Question 859539
You cannot tell what the measure of both sides are just given the hypotenuse.
{{{A^2+B^2=3.2^2}}}
You can choose one and calculate the other. 
If I choose A, then
{{{B=sqrt(3.2^2-A^2)}}}
For example, 
{{{A=1}}}
{{{B=sqrt(10.24-1)=3.04}}}
and if
{{{A=2}}}
{{{B=sqrt(10.24-4)=2.50}}}
So you have to choose one and solve for the other, you can't solve for both.
