Answer:

  (6)  KL = 1

  (7)  x = -4

  (8) x = 6

Step-by-step explanation:

(6) The diagram shows us ...

  KL +12 = 13

  KL = 1 . . . . . . . . . . subtract 12

__

(7) Similarly, the sum of the parts is equal to the whole:

  9 +(2x +9) = (x +14)

  x +4 = 0 . . . . . . . . . . . . . subtract (x+14) and simplify

  x = -4

__

(8) As with segments, so with angles: the sum of the parts is equal to the whole.

  ∠GHA +∠AHI = ∠GHI

  (8x +2) +(13x +9) = 137

  21x = 126 . . . . . . . . . . . . . . subtract 11

  x = 126/21 . . . . . . divide by 21

  x = 6
