Step-by-step explanation:

The fact that GH is the perpendicular bisector of EF means EM = FM and all of the angles at M are congruent.

It does not say anything about the relative sizes of HM and GM, so we cannot conclude HM and GM are congruent.

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
