| Column A | Column B |
| 5 | AB |
- A. if the quantity in Column A is greater
- B. if the quantity in Column B is greater
- C. if the quantities are equal
- D. if the relationship cannot be determined from the information given
Correct Answer: B
Explanation:
The correct answer is (B). The sum of the angles of a triangle equals 180°. Thus,
x + 2x + 90° = 180°
3x = 90°
x = 30°
Therefore 
ABC is a 30°-60°-90° right triangle. In a 30°-60°-90° right triangle the hypotenuse is equal to twice the side opposite the 30° angle.
AB = 8
8 > 5
Column B > Column A
