What is the value of f? −18f−34−14f=11a. −31 1/3b. −231/2c. 23 1/2d. 31 1/3

-18f - 34 - 14f = 11

      -34 - 32f = 11

             -32f = 45

                          =

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

your answer is the frist one
