Answer:D

Step-by-step explanation:I just took the test. 🙂

Given that the point (12,-5) which takes the form (x,y), This implies that:

opposite=-5

adjacent=12

thus using using Pythagorean theorem, the hypotenuse will be:

c^2=a^2+b^2

plugging the values we obtain:

c^2=(12)^2+(-5)^2

c^2=144+15

c^2=169

thus

c=13

but

cosu03b8=adjacent/ hypotenuse

therefore:

cosu03b8=12/13

Answer is option . D
