The function h(x) is given below.
h(x) = {(3,-5), (5, -7), (6,-9), (10,-12), (12,-16)}
which of the following gives h '(x)?
o {(3,5), (5, 7), (6,9), (10, 12), (12, 16)}
o {(-5, 3), (-7,5), (-9, 6), (–12, 10), (–16, 12)}
{(3,-5), (5, -7), (6,-9), (10,-12), (12,-16)}
o {(5, 3), (7,5), (9, 6), (12, 10), (16, 12)}

answer: i believe its b. if you sound out the sentences that sounds wrong.

< 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)
