B) angle addition postulate
C) definition of congruence
D) definition of vertical angles

Second drop down options:
A) 2x = 56
B) 2x = 58
C) 2x = 204
D) 2x = 304

Answer 1

The property used to solve the equation 2x = 56 is the addition property of equality. We can solve this equation by performing the same operation on both sides of the equation to maintain equality.

Step-by-step explanation:

The property used to solve the equation 2x = 56 is the addition property of equality.

We can solve this equation by performing the same operation on both sides of the equation to maintain equality.

In this case, we need to isolate the variable x by subtracting 56 from both sides: 2x - 56 = 56 - 56. This simplifies to 2x = 0.

Therefore, the correct equation is 2x = 0.
