Solve for the value of x.
(8x+2)
34°

x = 18

Step-by-step explanation:

The angle of a straight line is 180°, if we already know that one of the two angles is 34°, then the other angle must be equal to (180 - 34) = 146°

To solve for x

8x + 2 = 146; subtract 2 from both sides

8x = 144; divide by 8

x = 18

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
