Z = 25. y = 101. I got this because of the parallel lines theorem. In essence, what this theorem means is that the alternate exterior angles are congruent. If you see, this means that 6z - 71 = 79. After solving this equation, you get z = 25. y = 101 because of supplementary angles. Z is 25, but the value of that angle is not 25 because first, you have to solve the equation, in which you get 79. 180 - 79 = 101.
Z = 25.
Y = 101.
Basing on the table, in each row, if you divide the cost by the number of people, all of them will yield 55. This means that each person, whether as an individual or in a group, must pay $55 in order to rent a fishing charter boat.
