Celine's cereal company is launching a new brand of cereal and she is considering two different

sizes for the base of the boxes.

box 1: the length is 3 times the width.

box 2: the length is 1 less than 4 times the width

the dimensions of the base of box 1 are:

width: x; length: 3

width: x; length: x + 3

width: x; length: x-3

width: x; length: 3x

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
