Question

Mathe help #2 lots of points help please

Answer 1

Medians bisect eachother at centroid in ratio 2:1

• ZS=XS=80

SU is perpendicular bisector

UY=UZ

So

• YZ=2(66)=132

Apply Pythagorean theorem

$\\ \tt\hookrightarrow VY^2=XS^2-VS^2=80^2-48^2=6400-2304=4096\implies VY=64$

Answer 2

Answer:

XS = 80

YZ= 132

VY = 64

Step-by-step explanation:

Firstly, SU is a perpendicular bisector

so, UV= UZ and YZ = 2(66) = 132

Each median bisect each other at centre with the ratio 2 : 1

therefore ZS = 80 = XS

now , by using P.G.T

VY² = XS²-VS²

=> 80²-48²

=> 6400-2304

=> 4096

=> √4096

=> 64

VY = 64
