Question Bank - Geometry, Question 20

Please re-explain answer choice 2. I don't understand the answer. Sorry for the broad question.

(1) Angle ABC is 90 degrees.

(2) The area of the triangle is 30.

(2) INSUFFICIENT: If the area of triangle ABC is 30, the height from point C to line AB must be 12 (We know that the base is 5 and area of a triangle = 0.5 Ã— base Ã— height). There are only two possibilities for such such a triangle. Either angle CBA is a right triangle, and CB is 12, or angle BAC is an obtuse angle and the height from point C to length AB would lie outside of the triangle. In this latter possibility, the length of segment BC would be greater than 12.

Please don't forget to post the complete text of the problem; you only have the two statements listed above! :)
