Question

8. For angle A it is known that cos(A)<0 and csc(A)=10. If A is drawn in standard position, in which

quadrant does its terminal ray lie?

Answer 1

The second quadrant.

Explanation:

If cos A is negative it is in either QII or QIII.

If csc is positive so is the sine so its in QI or QII.

So to satisfy both conditions the answer is QII.
