which is a property of an angle?
has two sides that each extend forever in both directions
has two endpoints
has two center points
has two rays that share a common endpoint

- Fourth option is correct. An angle has two rays that share a common endpoint .

⇒An angle has two rays that share a common endpoint .

The two rays of an angle are called the sides of the angle .

The common endpoint of the two rays in an angle is called the vertex of the angle.

Angles formed by two rays lie in a plane.

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
