Answer:

Option 1. (-5, 12)

Step-by-step explanation:

Here given values of the angles are csc∅ = 13/12 Or sin ∅ = 12/13

sec ∅ = -13/5 Or cos ∅ = -5/13

cot ∅ = -5/12 Or tan ∅ = -12/5

As we know cos ∅ = x-coordinates / y-coordinates which = negative value

tan ∅ = y-coordinates / x - coordinates = negative value

Now we can say the angle lies in second quadrant. So the point (x, y) will be  (-5, 12).

Therefore answer is option 1.
