Given that tan θ= -65/72 and that angle θ terminates in quadrant II, then what is the value of cos θ?

adoni [48]

Answer:

cosθ = $-\frac{72}{97}$

Step-by-step explanation:

tanθ = -(65/72)

If it is in the 2nd quadrant, this means that y is positive but x is negative

tanθ= opposite/adjacent or (y/x)

tanθ= $\frac{65}{-72}$

We know that the adjacent value = -72 and the opposite value = 65

The hypotenuse can be get by the following

$\sqrt{(65)^2+(-72)^2} = 97$

cosθ is just adjacent/hypotenuse

Our adjacent value is -72

Our hypotenuse is 97, therefore

cosθ = $-\frac{72}{97}$
