13 and 14 degrees

Step-by-step explanation:

Step-by-step explanation:

x+6 = -6+4x

4x-x = 6+6

3x = 12

x =12/3

x = 4

Substituting x into the value of CH:

-6+4(4)

= -6 + 16

CH = 10

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

16 is the absolute value
