Answer:

D.   -\sqrt{17}/8

Step-by-step explanation:

Draw a right triangle such that cos (theta) = 8/9.  That means the hypotenuse = 9 and the adjacent side to theta = 8

Use the Pythagorean theorem to find the opposite side to theta

\sqrt{9^{2} - 8^{2} }  = \sqrt{81 - 64}  = \sqrt{17}

tan (theta) = \sqrt{17}/8

Since theta is in quadrant IV, the tan is negative.  So, tan (theta) = -\sqrt{17}/8
