(Page 31, Question 60, Answers: Page 57, Test 2)

Choices F, G, and H are inapplicable because this is not a right triangle.

"In a triangle, the largest angle is opposite the longest side, and the smallest angle is opposite the shortest."

Considering the aforementioned fact and applying the Law of Cosines, the shortest side, which is 14 cm, must be on the left side of the equation sign ("="), so choice J is correct.
