b=135 because opposite angles of a parallelogram are congruent is correct because the angles are opposite each other in the parallelogram and congruent means equal so angle b must equal 135.
I'm guessing we are solving for a unknown variable? This question is hard to understand, if you are not solving for a unknown variable than tell me in the comments and ill fix my answer
(X*4-14)*6=18
If I am correct your answer is 4.25
(4.25x4-14)*6=18
If I did the problem wrong than tell me. To me this question makes no sense so i'm not sure if I did it wrong.
