Question

∆XYZ~∆DEF, XY=5.1cm. YZ=3.9, XZ=6cm, XY:DE=3.2 construct ∆XYZ, and ∆DEF​

Answer 1

Answer :

XYZ-DEF

XY:DE=3:2

THEREFORE

YZ:EF=3:2 &

XZ:DF=3:2

let x=DE

3/2=5.1/x

x=5.1×2/3

x=10.2/3

x=3.4

XY=3.4cm

let y=EF

3/2=3.9/y

y=3.9×2/3

y=7.8/3

y=2.6cm

let z=DF

3/2=6/z

z=6×2/3

z=12/3

z=4cm
