Application +4 | -1

\frac{\cos A}{3}=\frac{\cos B}{4}=\frac{1}{5}-\frac{\pi}{2} < A < 0

and

-\frac{\pi}{2} < B < 0

, then the value of

2 \sin A+4 \sin B

View answer and explanation

Correct option: C

-4

Option C (-4) is correct because it is the result of calculating

2 \sin A + 4 \sin B

using the given conditions and quadrant information.
