Question

Find the value of cos F rounded to the nearest hundredth, if necessary. E 6 F 8 10 D​

Answer 1

cosF = 0.6

Explanation:

cosF =
`(adjacent)/(hypotenuse)` =
`(EF)/(DF)` =
`(6)/(10)` = 0.6

Answer 2

Cos F = 0.6

Explanation:

Trigonometry ratios:

`\sf \boxed{\bf \ Cos \ F = (adjacent \ side \ of \ \angle F)/(hypotenuse)}`

`\sf =(EF)/(DF)\\\\=(6)/(10)\\\\= 0.6`
