Answer:

Step-by-step explanation:

Each one of the trig functions is plus in two quadrants.

The sin(theta) is plus in 2

The Tan(theta) is plus in 3

The cos(theta) is plus in 4

Rule: if the trig function is not plus, then it is minus.

So if Tan (theta) is minus it means theta is in quad 2 or quad 4

So in this case theta is either in quad 2 or quad 4.

The sin is plus, that means that theta is in quad 2.
