Please help me with this math problem :)

x = 36

Step-by-step explanation:

180 - 48 = 132

This is because angle AC- and ACB form a straight angle (180 degrees).

132 + 12 = 144

180 - 144 = 36

The three interior sides of a triangle always add up to 180 degrees.

Hope this helps!

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
