Answer:
k = -1
Step-by-step explanation:
6(5k-8)-20= 11(2k-3)+3k | Given
30k - 48 - 20 = 22k - 33 + 3k | Distribute
30k - 28 = 25k - 33 | Add numbers & combine like-terms
30k = 25k - 5 | Add 28 to both sides
5k = -5 | Subtract 25k from both sides
k = -1 | Divide -5 by 5

Answer:
AB = 17 meters
Step-by-step explanation:
Given that the triangle, ∆ABC, has 2 congruent sides that are indicated with a single marking on segment AC and segment AB, both segments would be of equal measure.
Therefore, since the measure of segment C is 17 meters, the measure of segment AB = measure of segment AC = 17 meters.
Segment AB = 17 meters. It is congruent to segment AC.
