Question

What is the cosine ratio for angle F?

Answer 1

ANSWER

$\cos( \angle \: F) = \frac{5}{13}$

EXPLANATION

The side length adjacent to <F is 5 units.

The length of the hypotenuse is 13 units.

The cosine ratio is

$\cos( \angle \: F) = \frac{adjacent}{hypotenuse}$

This implies that:

$\cos( \angle \: F) = \frac{5}{13}$

The fourth choice is correct.
