Question

Look at the figure and answer

Answer 1

`\cos x=(8)/(f)`

Explanation:

Given that,

`\tan x=(e)/(8)\\\\\sin x=(e)/(f)`

We need to find the value of cos x.

We know that,

`\tan\theta=(\sin\theta)/(\cos\theta)`

Using the above relation,

`(e)/(8)=((e)/(f))/(\cos x)\\\\\cos x=((e)/(f))/((e)/(8))\\\\=(e)/(f)* (8)/(e)\\\\=(8)/(f)`

So, the value of cos x is equal to
`(8)/(f)`.
