15 POINTS!!!!!! Two angles are supplementary. Which of the following equations can be used to find the value of the missing angle, x, if the other angle is 67°?
x + 180° = 67°
x + 67° = 180°
x + 67° = 90°
x + 90° = 67°
The answer will be x + 67 = 180 because supplementary angles means that all of the angles will have to add up to 180, and the only choice that has 180 as one of the options is the second one
