begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell BC over FG end cell equals cell AB over EF end cell row cell 35 over 28 end cell equals cell 20 over EF end cell row cell fraction numerator space space space up diagonal strike 35 space space to the power of 7 over denominator 28 end fraction end cell equals cell fraction numerator space space space up diagonal strike 20 space space to the power of 4 over denominator EF end fraction end cell row cell 7 over 28 end cell equals cell 4 over EF end cell row cell fraction numerator up diagonal strike 7 over denominator space space space up diagonal strike 28 space space to the power of 4 end fraction end cell equals cell 4 over EF end cell row EF equals cell 16 space cm end cell row blank blank blank end table end style

 

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell BC over FG end cell equals cell AD over EH end cell row cell 35 over 28 end cell equals cell AD over 16 end cell row cell fraction numerator 35 over denominator space space space up diagonal strike 28 space space to the power of 7 end fraction end cell equals cell fraction numerator AD over denominator space space space up diagonal strike 16 space space space to the power of 4 end fraction end cell row cell 35 over 7 end cell equals cell AD over 4 end cell row cell fraction numerator space space space up diagonal strike 35 space space to the power of 5 over denominator up diagonal strike 7 end fraction end cell equals cell AD over 4 end cell row AD equals cell 20 space cm end cell row blank blank blank end table end style

 

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row DC equals cell square root of 15 squared plus 20 squared end root end cell row blank equals cell square root of 225 plus 400 end root end cell row blank equals cell square root of 625 end cell row blank equals cell 25 space cm end cell end table end style

 

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell BC over FG end cell equals cell DC over HG end cell row cell 35 over 28 end cell equals cell 25 over HG end cell row cell fraction numerator space space space up diagonal strike 35 space space to the power of 7 over denominator 28 end fraction end cell equals cell fraction numerator space space space up diagonal strike 25 space space to the power of 5 over denominator HG end fraction end cell row cell 7 over 28 end cell equals cell 5 over HG end cell row cell fraction numerator up diagonal strike 7 over denominator space space space up diagonal strike 28 space space to the power of 4 end fraction end cell equals cell 5 over HG end cell row HG equals cell 20 space cm end cell row blank blank blank end table end style

Jadi, jawaban yang tepat adalah begin mathsize 14px style EF equals 16 space cm end stylesize 14px HG size 14px equals size 14px 20 size 14px space size 14px cmsize 14px AD size 14px equals size 14px 20 size 14px space size 14px cm, dan begin mathsize 14px style DC equals 25 space cm. end style
