Question

How do you find the value of Secx= 5?

Answer 1

`Secx=5`

Explanation:

Given that `sec = 1/cos`, we can realize that `secx=5` is the same as `1/cosx=5`.

From there we multiply both sides with `cosx` and we get `1=5cosx` and now we simply divide both sides by `5` and we get `1/5=cosx`, now just get the `cos^{-1}` of `1/5` which is `78.46` in degrees or `1.3` in radians.
