Pembahasan

Jadi

$table attributes columnalign right center left columnspacing 0px end attributes row cell tan 105 degree end cell equals cell fraction numerator tan 60 plus tan 45 over denominator 1 minus tan 60 cross times tan 45 end fraction end cell row blank equals cell fraction numerator square root of 3 plus 1 over denominator 1 minus open parentheses square root of 3 cross times 1 close parentheses end fraction end cell row blank equals cell fraction numerator 1 plus square root of 3 over denominator 1 minus square root of 3 end fraction cross times fraction numerator 1 plus square root of 3 over denominator 1 plus square root of 3 end fraction end cell row blank equals cell fraction numerator 2 square root of 3 plus 4 over denominator negative 2 end fraction end cell row blank equals cell negative open parentheses 2 plus square root of 3 close parentheses end cell end table$

Jadi table attributes columnalign right center left columnspacing 0px end attributes row cell tan 105 degree end cell equals cell negative open parentheses 2 plus square root of 3 close parentheses end cell end table
