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
