Question 1156830
Can draw the altitude to the hypotenuse and have legs x and 5-x, and define x as the longer.
x^2+a^2=16, for one triangle
(5-x)^2+a^2=9
subtracting, one gets x^2-(5-x)^2=7
this works out to x=3.2 and 5-x=1.8 units inches.  These can be shown to be consistent with the Pythagorean theorem for both triangles.
