10. Find TU :

Given values :

  • ST = 4 units

  • SU = 12 units

As we saw :.

  • ST + TU = SU

  • 4 + TU = 12

  • TU = 12 - 4

  • TU = 8 units

11. Find TU :

Given values :

  • ST = 2 units

  • UV = 7 units

  • SV = 19 units

According to observation :

  • ST + TU + UV = SV

  • 2 + TU + 7 = 19

  • TU = 19 - 9

  • TU = 10 units
