Label the side lengths, relative to the given interior (acute) angle, using a, o and h (label both the given side length as well as the one you're trying to find).
Given a right angle triangle, the method for finding an unknown angle a, can be summarized in three steps : 36 6 = x 10. Just find the voltage of the known resistor w/ the ohmemeter, and use ohm's law (i=v/r) to get the current, then use the current with the unknown r's voltage & ohm's law to get the resistance.
