A) The value of x should be 105, because the angles shown in the diagram are complementary. B) The value of x should be 75, because the angles shown in the diagram are supplementary.

C) The value of x should be 75, because the two angles shown in each diagram are obtuse angles.

D) The value of x should be 105, because the angles shown in the diagram are supplementary.

yes

yes yes yes

you would need to know all the numbers that are on there

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
