when ryan walks into the auditorium, there are 5 available seats in the first row, 10 in the second row, and 2 in the third row. ryan randomly selects a seat.

what is the probability, to the nearest percent, that his seat will be in the first row?

a)29%
b)42%
c)58%
d)71%

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
