Sagot :
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...!!!!!
