There is a pair of vertical angles whose measures are m∠1=106° and m∠2=(3x−75)° . What equation can you write to solve for x ?

Responses:
3x° − 75° + 106° = 90°
3x° − 75° − 106° = 180°
3x° −75° = 106°
3x° − 75° + 106° = 180°

The correct equation to solve for x is:

m∠1 = m∠2 (since they are vertical angles)
106° = (3x - 75)°
