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

Angle LJK is at J, so its adjacent side is LJ (10) and the hypotenuse is JK (15). Cosine = adjacent/hypotenuse, so

cos(x) = 10/15.
