At the end of class on Wednesday I asked 2 questions regarding section 6.2 problem #11 on page 288. Here are the two questions and answers.
Does the "b2" in the question refers to the area of the triangle or is it some reference to the area of one leg squared (as in "a2 + b2 = c2) ?
Answer #1: "b2" is the area of the triangle.
Gerbert's answer is two solutions, the two answers are related to the 1 correct?
Answer #2: yes
