Triangle L J K is shown. Angle J L K is a right angle. The length of the hypotenuse is 15 inches and the length of the side adjacent to the right angle is 10 inches. The angle between the 2 sides is x.

Which equation can be used to find the measure of angle LJK?

sin(x) = Ten-fifteenths
sin(x) = Fifteen-tenths
cos(x) = Ten-fifteenths
cos(x) = Fifteen-tenths

cos(x) = Ten-fifteenths

Reason: For angle LJK (at J) the adjacent side is 10 and the hypotenuse is 15, so cos x = adjacent/hypotenuse = 10/15 (which simplifies to 2/3).
