Answer:
cosθ =
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=
We know that the adjacent value = -72 and the opposite value = 65
The hypotenuse can be get by the following
cosθ is just adjacent/hypotenuse
Our adjacent value is -72
Our hypotenuse is 97, therefore
cosθ =
