Angle AOC and angle BOD are vertical angles. If m∠AOC = (4x + 40)° and m∠BOD = 120°, which equation could be used to solve for x?(2 points)
Responses
x + 40° = 120°
x + 40° = 120°
(4x)° = 120°
(4 x )° = 120°
(4x + 40)° = 120°
(4 x + 40)° = 120°
4x + 120° = 40°
The correct equation to solve for x is:
4x + 40° = 120°
