Question: 596

7. If b = 45, then v² =

A. 32
B. 25
C. 16
D. 5

Correct Answer: A

Explanation:

If bo = 45o, the other angle must also be 45o since 180 - 90 - 45 = 45, which makes this an isosceles right triangle. Therefore, the other leg of the triangle is also 4. From here, use the Pythagorean Theorem to find v²: 4² + 4² = v². Simplify the left side of the equation to get 16 + 16 = 32. The correct answer is (A).
