25. according to the line graph below, between which two consecutive years was there the greatest change in the number of 3-d movies released? number of 3-d movies released by year number of 3-d movies released 2003 2004 2005 2006 2007 2008 2009 2010 2011 yea a. 2003-2004 b. 2008-2009 c. 2009-2010 d. 2010-2011

the answer to this question is yes

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

< 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)
