URGENT: If θ is a second-quadrant angle and cosθ = -2/3, then tanθ = _.

In the second quadrant, both cos and tan are negative while only sin is positive.

To find tan, we will use the following property below:

Sec is the reciprocal of cos. If cos is a/b then sec is b/a. Since cos is 2/3 then sec is 3/2

Since tan is negative in the second quadrant. Hence,

Answer

ratio is 2 : 9

the answer is three

13.5 : 3
