For an angle θ with the point (12, −5) on its terminating side, what is the value of cosine?

The value of cosine is .

Step-by-step explanation:

It is given that  an angle , with the point (12,-5) is  on its terminating side, then the adjacent sides has measure =12 and the opposite side has measure =-5.

Now, from the figure drawn, using the Pythagoras theorem, we have

⇒

⇒

⇒

⇒

Thus, the value of hypotenuse is 13units.

Now, the value of cosine is given as:

⇒

Therefore, the value of cosine is .
