Given: mAngleORP = 80° mAngleORN = (3x + 10)° Prove: x = 30 3 lines are shown. A line with points P, R, N intersects a line with points M, R, O at point O. A line extends from point R to point L between angle M R P. Angle N R O is (3 x + 10) degrees and angle P R O is 80 degrees. Which statement could be used in step 2 when proving x = 30? A 2-column table with 5 rows. Column 1 is labeled statements with the entries measure of angle O R P = 80 degrees semicolon measure of angle O R N = (3 x + 10) degrees, blank, blank, blank, blank. Column 2 is labeled reasons with the entries given, blank, blank, blank, blank. AngleORP and AngleORN are a linear pair AngleORP and AngleORN are vertical angles 80 = 3x +10 x = 30
