Question

a right triangle has side lengths d,e, and f as shown below. Use these lengths to find cos x, sin x, and tan xcos x=sin x=tan x=

Answer 1

We have,

`\begin{gathered} \cos x=\frac{adjacent\text{ side}}{hypotenuse} \\ \sin x=\frac{\text{opposite side}}{hypotenuse} \\ \tan x=\frac{oppositeside}{adjacent\text{ side}} \end{gathered}`

So here,

`\begin{gathered} \cos x=(d)/(f) \\ \sin x=(e)/(f) \\ \tan x=(e)/(d) \end{gathered}`
