Berdasarkan gambar berikut, tentukan nilai  dan .

Berdasarkan gambar berikut, tentukan nilai x degree dan y degree.


 begin mathsize 14px style space end style 

Jawaban:

Jumlah sudut dalam segitiga adalah 180 degree, maka nilai x degree:

table attributes columnalign right center left columnspacing 0px end attributes row cell 60 degree plus 80 degree plus x degree end cell equals cell 180 degree end cell row cell x degree end cell equals cell 180 degree minus open parentheses 60 degree plus 80 close parentheses end cell row cell x degree end cell equals cell 180 degree minus 140 degree end cell row cell x degree end cell equals cell 40 degree end cell end table 

Sudut berpelurus berjumlah 180 degree.

sudut x degree berpelurus dengan sudut y degree, maka nilai y degree:

table attributes columnalign right center left columnspacing 0px end attributes row cell x degree plus y degree end cell equals cell 180 degree end cell row cell y degree end cell equals cell 180 degree minus x degree end cell row cell y degree end cell equals cell 180 degree minus 40 degree end cell row cell y degree end cell equals cell 140 degree end cell end table 

Jadi, table attributes columnalign right center left columnspacing 0px end attributes row blank blank x end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank degree end table table attributes columnalign right center left columnspacing 0px end attributes row blank equals blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 40 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank degree end table dan table attributes columnalign right center left columnspacing 0px end attributes row blank blank y end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank degree end table table attributes columnalign right center left columnspacing 0px end attributes row blank equals blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 140 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank degree end table.
