8. triangle abc has vertices a(-2, 5),
b(1,0), and c(6, -2). what are the
coordinates of the vertices of
triangle a'b'c' for rx=4

A'(10,5), B'(7,0), C'(2,-2)

Step-by-step explanation:

Triangle ABC with vertices A(-2, 5), B(1,0), and C(6, -2) is reflected across the line x=4.

This reflection has the rule

So,

See attached diagram for details.

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
