Answer:
x=3
Step-by-step explanation:
Given,
1 = 1/(x-2)
Multiply both sides by (x-2),
1*(x-2) = 1/(x-2) * (x-2)
x-2 = 1
Adding 2 on both sides,
x-2+2 = 1+2
x = 3
 
        
             
        
        
        
It is 9:4.
Reason: divide both numbers by a common multiple, which is 7. 
        
             
        
        
        
F(x)=2x
G(x)=x+5
Now 
F(g(x))=2(x+5)
=2x+10
G(f(x))=2x+5

Answer:
Option B Yes by AAA
Step-by-step explanation:
we know that
If the two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent
so

substitute the values and verify

simplify
 -------> is true
 -------> is true
therefore
The triangles are similar by AAA------> the three angles are congruent
