Answer:

x = 30°

Step-by-step explanation:

m∠ONK = 180° (straight angle)

∠ONM + ∠MNL + ∠LNK = 180° (supplementary angles)

105° + 45° + m∠LNK = 180° (substitution)

m∠LNK = 30° (algebra)

m∠LNK + m∠NLK + m∠LKN = 180° (sum of interior angles of a triangle)

30° + 90° + 2x = 180° (substitution, m∠NLK = 90° bc supplementary angles; other supp. angle is 90°)

120° + 2x = 180°

2x = 60°

x = 30°

X=30. I hope it helps
