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.

Answer:

second quadrant

Step-by-step explanation:

sin A > 0 ⇒ first/ second quadrant

cos A < 0 ⇒ second/ third quadrant

The second quadrant is common to both, thus A terminates in the second quadrant.
