Mr. DeWitt carved a wooden boat for his granddaughter. He began with a piece of wood that was 20.3 centimeters long. The boat is 16.7 centimeters long. How many centimeters did Mr. DeWitt carve off the length of the wood when he made the boat?pls help me answer this giving brainless to somone.​

f(x)=2/3x-8, which give g(x) the greatest value.

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)

just get this app called photo math it should be able to do those
