Answer:

Step-by-step explanation:
Since Θ is in fourth quadrant then cosΘ > 0, as is secΘ
Given
sinΘ = -
, then
cosΘ = 
=
=
= 
Hence
secΘ =
=

|x|=-11
Which is a contradiction since, the |x| is always a positive number
Attached is the representation of this function y= |x|
It means, that it doesnt matter what value 'x' has, the answer is the same number but, positive
