Question

What is the cosine ratio for angle F?

Answer 1

`\cos( \angle \: F) = (5)/(13)`

Step-by-step 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) = (adjacent)/(hypotenuse)`

This implies that:

`\cos( \angle \: F) = (5)/(13)`

The fourth choice is correct.
