F(x)=(x-8)/(x+7). g(x)=(-7x-8)/(x-1). Plug in g(x) into f(x), f(g(x))=[(-7x-8)/(x-1)-8]/[-7x-8)/(x-1)+7], which can be simplified as (-7x-8-8x+8)/(-7x-8+7x-7)=-15x/-15=x. Plug in f(x) into g(x), g(f(x))=[-7*(x-8)/(x+7)-8]/[(x-8)/(x+7)-1]=(-7x+56-8x-56)/(x-8-x-7)=-15x/-15=x, as desired.

Answer:
Option 3: transitive property
Step-by-step explanation:
The previous statements are
2. ∠2 ≅ ∠3 ⇒ 2. ver. ∠s theorem
And
5. m∠3 = m∠7 ⇒ 5. def. of congruent
So, The previous proved statement to make use of the transitive property reason or proof
∴ 6. m∠2 = m∠7 ⇒ 6. transitive property
Note: the transitive property states that: If a = b and b = c, then a = c.
