Question

A right triangle has side lengths d, e, and f as shown below.

Use these lengths to find tanx, sinx, and cosx.

Answer 1

tan x =
`(f)/(e)`

sin x =
`(f)/(d)`

cos x =
`(e)/(d)`

Explanation:

tan x =
`(opposite)/(adjacent)`

tan x =
`(f)/(e)`

sin x =
`(opposite)/(hypotenuse)`

sin x =
`(f)/(d)`

cos x =
`(adajcent)/(hypotenuse)`

cos x =
`(e)/(d)`
