Answer :

Answer:

C. [tex] \frac{8\sqrt{89}}{89} [/tex]

Step-by-step explanation:

Cos A = Adj/Hyp

Reference angle =

Adjacent side = 8 ft

Hypotenuse = √(8² + 5²) = √89 (pythagorean theorem)

Thus:

[tex] Cos (A) = \frac{8}{\sqrt{89}} [/tex]

Rationalize

[tex] Cos (A) = \frac{8 * \sqrt{89}}{\sqrt{89} * \sqrt{89}} [/tex]

[tex] Cos (A) = \frac{8\sqrt{89}}{89} [/tex]
