Луч \(\displaystyle OC\) делит развернутый угол \(\displaystyle ∠ AOB\) на два смежных угла \(\displaystyle ∠ AOC\) и \(\displaystyle ∠ BOC\) так, что угол \(\displaystyle ∠ AOC\) на \(\displaystyle 120^{\circ}\) меньше угла \(\displaystyle ∠ BOC\). Чему равны углы \(\displaystyle ∠ AOC\) и \(\displaystyle ∠ BOC\)?

• \(\displaystyle ∠ AOC=60^{\circ}\), \(\displaystyle ∠ BOC=120^{\circ}\)
• \(\displaystyle ∠ AOC=30^{\circ}\), \(\displaystyle ∠ BOC=150^{\circ}\)
• \(\displaystyle ∠ AOC=15^{\circ}\), \(\displaystyle ∠ BOC=135^{\circ}\)
• \(\displaystyle ∠ AOC=75^{\circ}\), \(\displaystyle ∠ BOC=105^{\circ}\)
