Question

What is the cosine ratio for ∠F? p.s. show how you got your answer!

Answer 1

6/10 its adjacent over hypotenuse

Answer 2

cosF =
`(3)/(5)` is the answer.

Explanation:

In a right angle triangle cosine of any angle =
`(Base)/(Hypotenuse)`

In the given triangle base or adjacent side of the angle is = 6

Hypotenuse given as 10

So by putting the values of hypotenuse and base in the formula

∠F =
`(6)/(10)=(3)/(5)`

Therefore cosine of angle
`cosF=(3)/(5)` is the answer.
