Name a set of vertical angles in the image below: A. 2 and 3
B. 1 & 3
C. 1 & 4
D. 4 & 3

Explanation:

Vertical angles form when we have an X shape like this. They are opposite one another and always congruent. Angles 2 and 4 is the other set of vertical angles.

B. 1 & 3

Step-by-step explanation:

The vertical angles are pairs of opposite angles made by 2 intersecting lines. Here, 1 and 3 are the same length, and are on opposite sides.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
