If A + B = \(90^\circ\), and sin A =\(\frac{5}{13}\), then what is cos B?
If A + B = \(90^\circ\), and sin A =\(\frac{5}{13}\), then what is cos B?
A + B = \(90^\circ\), और sin A = \(\frac{5}{13}\), तो cos B क्या हैं?
Detailed Solution & Logic
Correct Answer:
\(\frac{5}{13}\)
$A + B = 90^\circ $,
$B = 90^\circ - A $,
$\cos B = \sin A = \frac{5}{13}$
$\cos B = \frac{5}{13}$
