If you draw the triangle on a sheet of graph paper, you will notice that the smallest angle is the one opposite the shortest side.

This is true for all triagles, not just right triangles.

Since the shortest side is 5, you'll want to find the angle opposite this side.

From that angle, the opposite side is 5 and the adjacent side is 9.

You have three trig formulas -- the one that has both opposite and adjacent in it is tangent.

tan(angle)  =  opp/adj     ---     tan(angle)  =  5/9     --->     angle  =  tan--1( 5/9 )

Now, use a calculator to find the answer.
