Answer:

  • w = 46

Step-by-step explanation:

  • V is the midpoint of RU, so VU = 1/2 RU
  • T is the midpoint of SU, so UT = 1/2 SU

And we have:

  • RS = w, or
  • RU + SU = w

Also we have:

  • TV = w - 23,

or substitute as above given:

  • VU + UT = w - 23
  • 1/2 RU + 1/2 SU = w - 23
  • 1/2 (RU + SU) = w - 23
  • 1/2 w = w - 23
  • w - 1/2 w = 23
  • 1/2 w = 23
  • w = 23*2
  • w = 46

Answer:

ST+TU=SU

ST=TU

SU/2=ST=TU

5x-2=3x-4

2x=-2

x=-1

ST=5x-2=5(-1)-2=-5-2=-7 --->|ST|=7

TU=3x-4=3(-1)-4=-3-4=-7 --->|TU|=7

ST+TU=SU ---> 7+7=14

hope it's help you...!!!!!

plz mark as brain list and thanks for following me #rishu.....!!!!!!!!!!
