18 is the length . Your welcome :)
I think the answer is B it would be a vertical line with the rise/run for finding slope
Solve the equation for x by finding a, b and c of the quadratic then applying the quadratic formula
Answer:
See Below.
Step-by-step explanation:
Paragraph Proof:
We are given that ∠1 ≅ ∠4. ∠1 and ∠4 are alternate exterior angles. Since they are congruent, by the Alternate Exterior Angles Converse, the two lines being cut by the transversal must be parallel. Then by the Alternate Interior Angles Theorem, ∠3 ≅ ∠2.
2-Column Proof
Statements Reasons:
1)
Given
2)
Alternate Exterior Angles Converse
3)
Alternate Interior Angles Theorem
I would write a flowchart as well, but unfortunately, I never learned it that way.
