Answer:
statement D is correct.
<em>Statement: ∠7 ≅ ∠6 and ∠8 ≅ ∠5</em>
<em>Reason: Vertical Angles Theorem</em>
Step-by-step explanation:
Given that 
3 ≅ ∠7 and ∠4 ≅ ∠8
from statement 2 because they are corresponding angles. 
∠8 ≅ ∠5 
because its vertical angles
The vertical angles theorem is about angles that are opposite each other.
 So,
 ∠4 ≅ ∠8 and ∠8 ≅ ∠5 
which means 
<h3> ∠4 ≅ ∠5 </h3>
Hence,
∠3 = ∠7
∠4 = ∠5
 they are known as interior alternative angles.
 
        
             
        
        
        
Answer:
x=1
Step-by-step explanation:
Look at the bottom of the triangle you will see that 1 = x
 
        
             
        
        
        
2 times 2=4
multiply first equation by 2 to get
-4x+6y=12
then add to get
-4x+6y=12
<u>4x-2y=8 +</u>
0x+4y=20
4y=20
y=5
sub back
-2x+3y=6
-2x+3(5)=6
-2x+15=6
-2x=-9
x=9/2=4.5
the number to multiply by is 2
