SAT Scores 250 300 350 400 450 500 550 600 650 700 750 800 Use the table of SAT scores to answer the following questions: a) Someone who scored a 500 was at the Enter you answer in accordance to the item a) of the question statement th percentile. b) Enter you answer in accordance to the item b) of the question statement % of people scored between 650 and 700. c) If you are at the 88th percentile, what was your score? Enter you answer in accordance to the item c) of the question statement d) Approximately, what is the first quartile for SAT scores? The third quartile? Q1 =

< 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)

ok thats very interesting
