Answer» Answer: Just remember the cosine of an angle is the side ADJACENT to the angle divided by the HYPOTENUSE of the TRIANGLE. In the diagram, the adjacent side is a and the hypotenuse is c , so cosθ=ac . To find θ , you use the arccos FUNCTION, which has the same relationship to cosine as arcsin has to sine.
