Use the similar triangles above to find x. Then find the measure of KM.

• x = 2

  KM = 6

• x = 2

  KM = 4

• x = 4/3

  KM = 5 1/3

• x = 3

  KM = 7

Use the similar triangles above to find x. Then find the measure of RP.

• x = 12

  RP = 21

• x = 12

  RP = 14

• x = 2.5

  RP = 2

• x = 2.5

  RP = 4.5
