<u>Answer</u>
-3/√13
<u>Explanation</u>
We are going to take angle ∅ to be at the origin (point (0,0)).
The point at (-2, -3) means, 2 units to the left (negative side of x-axis) and 3 units downwards (negative side of y-xis).
This will make a right triangle with a hypotenuse of √(2²+3²) = √13
The angle ∅ is in the 3rd quadrant where cosine is negative.
cosine = adjacent/hypotenuse
The exact answer for cos ∅ = -2/√13
