80
Step-by-step explanation:
you just do the actual equation!
 
        
                    
             
        
        
        
Let's solve for x.
y
=
x
+
2
−
4
Step 1: Flip the equation.
x
−
2
=
y
Step 2: Add 2 to both sides.
x
−
2
+
2
=
y
+
2
x
=
y
+
2
Answer:
x
=
y
+

Answer:
see below
Step-by-step explanation:
Angle ACE = DCE since they are vertical angles
Angle A = Angle E parallel lines cut by a transversal form congruent alternate interior angles
Angle B = Angle D parallel lines cut by a transversal form congruent alternate interior angles
When all three angles are equal, the triangles are similar.
We can use ratios to find DE
DE         CE  
------- = ----------
AB           AC
DE         8
------- = ----------
12           10
Using cross products
10 DE = 8*12
10 DE = 96
Divide by 10
DE = 9.6
