29. The smallest angle, ∠C, is opposite the shortest segment, AB or BA. None of the inequalitites that show that segment as being greater than any of the others can be true.
On the other hand, the largest angle, ∠B, is opposite the longest segment, AC. Any inequality that shows it greater than either of the others will be true.
The appropriate choice is
B) AC > BC
30. The volume is the product of length, width, and height. Since the two volumes are equal, the height (h) will satisfy the equation
25×9×12 = 15×15×h
2700/225 = h = 12
The height of the second prism is
C) 12
