Answer 1

In proving that x = 30, the statement that could be used in step 2 is: A. ∠ORP and ∠ORN are a linear pair.

What is a Linear Pair?

• When two angles lie on a straight line, they form a linear pair.
• The sum of the two angles that form a linear pair = 180 degrees.

Thus:

∠ORP and ∠ORN are angles on a straight line, and they form a lienor pair.

Therefore, in proving that x = 30, the statement that could be used in step 2 is: A. ∠ORP and ∠ORN are a linear pair.
