A and D

Step-by-step explanation:

A) 10+2^3*4-1                     D) 10+(2^3*4)-1

10+8*4-1                                  10+(8*4)-1

10+32-1                                   10+32-1

42-1                                         42-1

41                                             41

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
