Use trig functions to find x. Trig functions are special relationships which exits between the sides of right triangles. Since you need to find x the hypotenuse and you have the adjacent side to 77 degree angle use cosine.

Cos 77 = 19/x

0.22495 = 19/x

19/0.22495 = x

84.5 = x

Answer:

It is proved that $f(x)g(x)=|x|=|x-4|-4$ .

Step-by-step explanation:

Given functions are,

$f(x)=|x|$

$g9x)=|x-4|-4$

To show,

$f(x)g(x)=|x|=|x-4|-4$

Consider,

$(fg)(x)=f(g(x))=f(|x-4|-4)=||x-4|-4|$

now if,

$x>4\implies x-4>0$ then $(fg)(x)=||x-4|-4|=|x-4|-4$

$x$ then $(fg)(x)=||x-4|-4|=||-(x+4)|-4|=|x+4-4|=|x|$

Hence the reslt.
