The sides of AABC are 30 units, 40 units, and 60 units long. The corresponding sides of AXYZ are rtimes as long as the sides of AABC. If the area of AABC Is n square units, the area of AXYZ IS (130/r,130r, 130*r, 64r)The expression that gives the perimeter of AXYZ IS(n, nr, n(n*r),n+r) square units. ​

Step-by-step explanation:

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

1. sometimes

2. never true

3. sometimes

these are pretty self explanatory if you know what supp right and com angles are
