Answer
Find out the value of x.
To prove
By using the trignometric identity

As given in the diagram.

Perpendicular = x
Hypotenuse = 6
Put in the above identity


Put in the above

x = 4.6 cm (Approx)
Therefore Option (c) is correct .
Answer:
x≠-1,1
Step-by-step explanation:
f(g(x)) is a composition where g(x) is is substituted for x in f(x).
Recall, f(x) is 2/x. So we write 2/|x|-1. This places x in the denominator and 0 cannot be in the denominator x. Any value of x that makes the denominator 0 will not be in the domain.
|x|-1=0
|x|=1
x=1,-1
184+23=w
207=w
That’s the answer 207
