Final answer:
When sin A > 0 and cos A < 0, angle A terminates in the second quadrant.
Step-by-step explanation:
When sin A > 0 and cos A < 0, angle A terminates in the second quadrant. In this quadrant, the sine function is positive and the cosine function is negative.
The second quadrant is between 90° and 180°, where the x-coordinate (cosine) is negative and the y-coordinate (sine) is positive.
