A group of scientists studied the amount of erosion at a beach. The scientists determined that the equation y = -0.5x + 26 models the amount of shoreline, y, in feet, x decades after 1950. Which statement is true based on the model?
(A) The shoreline is reduced by 0.5 foot every 10 years,
B)
The shoreline is increased by 0.5 foot every 10 years.
The shoreline is reduced by 26 feet every 10 years.
The shoreline is increased by 26 feet every 10 years.

< 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)
