  1. 11 2 over 3 straight pi 

  2. 12 1 third straight pi 

  3. 12 2 over 3 straight pi 

  4. 13 1 third straight pi 

  5. 13 2 over 3 straight pi 

Jawaban:

Diketahui:

a equals 10 degree b equals 20 degree minus 10 degree equals 10 degree n equals 20 

Jumlah dari 10 degree plus 20 degree plus space... space plus 200 degree:

table attributes columnalign right center left columnspacing 0px end attributes row cell S subscript n end cell equals cell n over 2 open parentheses 2 a plus open parentheses n minus 1 close parentheses b close parentheses end cell row cell S subscript 20 end cell equals cell 20 over 2 open parentheses 2 open parentheses 10 degree close parentheses plus open parentheses 20 minus 1 close parentheses open parentheses 10 degree close parentheses close parentheses end cell row blank equals cell 10 open parentheses 20 degree plus 190 degree close parentheses end cell row blank equals cell 10 open parentheses 210 degree close parentheses end cell row blank equals cell 2.100 degree end cell end table 

Nilai dari 2.100 degree dalam radian:

table attributes columnalign right center left columnspacing 0px end attributes row cell 2.100 degree cross times fraction numerator straight pi over denominator 180 degree end fraction end cell equals cell 210 over 18 straight pi end cell row blank equals cell 70 over 6 straight pi end cell row blank equals cell 35 over 3 straight pi end cell row blank equals cell 11 2 over 3 straight pi end cell end table

Sehingga, hasil dari 10 degree plus 20 degree plus space... space plus 200 degree dalam radian adalah 11 2 over 3 straight pi.

Jadi, jawaban yang tepat adalah A.
