Answer:

  • KM = 29

Step-by-step explanation:

Use Intersecting chords theorem and find x:

  • JU * LU = MU * KU
  • 10*2x = 9(2x + 2)
  • 20x = 18x + 18
  • 2x = 18
  • x = 9

Find KM:

  • KM = 2*9 + 2 + 9 = 29

Step-by-step explanation:

➡JU×LU=MU×KU

➡10×2x=9(2x+2)

➡20x=18x+18

➡20x-18x=18

➡2x=18

➡x=18/2

➡x=9

KM=KU+UM

➡KM=9+2(9)+2

➡KM=9+18+2

➡KM=29
