<font face="Garamond" size="+2">


Presuming you mean the angle of elevation from the end of the shadow, otherwise the answer could be anything you like greater than zero and less than or equal to 90 degrees, (or *[tex \LARGE 0 < x \leq \frac{\pi}{2}] radians) use:



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \tan^{-1}{(\frac{150}{36})]
