3. Jim plotted the following ordered pairs on a coordinate grid. (1,3) (3,6) (7,6) (9,3) 9 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9 Jim connected the points with line segments to form a polygon. Which point is located inside the polygon?​

what i would say the best answer is a. 40.5

< 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)

answer: (-6,3)
