Answer:

  • x = 9
  • y = 12
  • u = 24
  • v = 32

Step-by-step explanation:

Each of the triangles is similar, so we have ...

  3/5 = (3+x)/20

  x = 20(3/5) -3

  x = 9

__

  4/5 = (4+y)/20

  y = 20(4/5) -4

  y = 12

__

  3/5 = (3 + x + u)/60

  u = 60(3/5) -3 -9

  u = 24

__

  4/5 = (4 +y +v)/60

  v = 60(4/5) -4 -12

  v = 32
