PLEASE HELP ASAP!!! I NEED CORRECT ANSWERS ONLY PLEASE!!!
amid [387]

Answer:

0.44

Step-by-step explanation:

This is a right angled triangle, so it yields:

                                             \cos \angle V = \frac{adjacent}{hypotenuse}

The value of <em>adjacent </em>is 39.

We will use the Pythagorean rule to obtain the length of hypotenuse:

                                         hypotenuse^2 = 39^2 + 80^2\\hypotenuse^2 = 1521 + 6400\\hypotenuse^2 = 7921\\hypotenuse = \sqrt{7921}\\hypotenuse = 89

Now we can insert that into \cos \angle V:

\cos \angle V = \frac{39}{89} =0.44
