sin(theta)<0

Explanation:

tan(theta)=opposite /adjacent

So, let's think about triangle in x and y coordinate

opposite = -2
adjacent = 3

so that triangle will be in the fourth part in the x and y coordinate

enter image source here

hypotenuse= sqrt((3)^2+(-2)^2)=sqrt5

So, sin(theta)=-2/sqrt5

sin(theta)<0
