Help me please I really need answers fast so I'd really appreciate your help I've been stuck on this since yesterday

Fill in each blank with a reason that justifies the statement.​ Given: ∠CDE and ∠EDF are supplementary.

Statement Reasons
m∠CDE + m∠EDF = 180° a. Definition of Supplementary Angles
x° + (3x + 60)° = 180° b. _________
4x° + 60° = 180° c. _________
4x° = 120° d. _________
x° = 30° e. _________
