Correct Answer: Option C
Explanation:
n = \(\frac{\sin \frac{1}{2} (dm + A)}{\sin \frac{1}{2} A}\)
= \(\frac{\sin \frac{1}{2} (40 + 60)}{\sin \frac{1}{2} \times 60}\)
= 1.532
n = \(\frac{\sin \frac{1}{2} (dm + A)}{\sin \frac{1}{2} A}\)
= \(\frac{\sin \frac{1}{2} (40 + 60)}{\sin \frac{1}{2} \times 60}\)
= 1.532
