The diagram above contains contradictory information. Explain the contradiction.
A. Since
Hence,–x-30+5x-30=180.
When you solve for x, your answer is x = 60.
m
The measurement of an angle cannot be a negative number for this problem.
B. Since
Hence, ,–x-30=5x-30.
When you solve for x, you get x = 0.
This would make m
The measurement of an angle cannot be 0° for this problem.
C. Since
Hence, ,–x-30+5x-30=180.
When you solve for x, you get x = 60.
This would make m
The measurement of an angle cannot be a negative number for this problem.
D. Since and are alternate interior angles, they are congruent. Hence, ,–x-30=5x-30.
When you solve for x, you get x = 0.
This would make m
The measurement of an angle cannot be a negative number for this problem.
