These results agree with our intuition. As we move farther north, away from the tropical regions, we would expect the angle of elevation of the sun to decrease.

At a latitude of $30^{\circ}$, the angle of elevation of the sun is $32.4^{\circ}$ At a latitude of $38.5^{\circ}$, the angle of elevation of the sun is $27.3^{\circ}$ These results agree with our intuition. As we move farther north, away from the tropical regions, we would expect the angle of elevation of the sun to decrease.
