Find the value of x. Express your answer in simplest radical form

Use Pythagorean Theorem which is a squared (one of the numbers thats side is with the 90° angle) plus b squared (the other number thats side is next to the 90° angle) equals c squared (the hypotenuse).

Step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
