Question

Can someone please help and explain

Answer 1

Step-by-step explanation:

median of a line devices the line in 2 equal parts

therefor,

TS=SR

RW=VW

and TU=VU

Answer 2

Step-by-step explanation:

for this you need to have knowledge about centroid in a triangle:-

so, centroid in a triangle is the centre point on which the 3 medians of the triangle intersect. And median is the centre point of the side of triangle on which it lies

here's the solution:-

TW is the median on RV

THEREFORE, RW=WV

WE KNOW RW = 6 =WV(RW+WV=12)

SIMILARLY, TS=RS

SINCE, RS=7.5=TS(TS+RS=11)

NOW, TV=11

SO, TU+UV=11

TU=UV

2TU=11

TU=11/2

TU=5.5=UV
