Answer 2

$\huge{\mathcal{\underline{\green{SOLUTION}}}} </p><p></p><p>$

$sin A + sin B = 2$

Since the maximum value of sine of an angle is 1

So

$sin A = 1 \: \: \: and \: \: \: \: sin B = 1$

So

$A \: = B = \frac{\pi}{2}$

Hence

$cos A + cos B = cos \frac{\pi}{2} + cos \frac{\pi}{2} = \: 0 + 0 = 0$
