Does this make a difference? In the last question we saw that Costco sells a large package of Kirkland toilet paper. It has 30 roles in it and costs $20.99. They also sell Cashmere; 40 rolls for $24.99. You may have determined the better deal based on the number of rolls BUT the Kirkland rolls are bigger - they have 425 sheets per roll whereas the Cashmere has 234 sheets per roll. How does this new information change your answer? HINT: Think unit cost!

step-by-step explanation:

< 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)
