Answer:
Explain Mistake Made
The equations are set up to equal 180 degrees rather than equal to each other
Correct Work & Answer
(7x - 3) = (6x + 17)
+ 3. + 3
7x = 6x + 20
-6x -6x
x = 20
Step-by-step explanation:
They should be set equal to each other because both angles are congruent. Let (7x - 3) be A and (6x + 17) B. Angle A is congruent with the angle opposite to angle B. The opposite angle creates a vertical angle with angle B, hence they are congruent. Therefore, angle A and B are congruent and should equal each other rather than be set equal to 180. That would only be the case if they were supplementary angles.
