The internal bisectors of the $angle straight B$ and $angle straight C$ of the $increment ABC$ , intersect at O. If $angle straight A space equals space 100 degree$ , then the measure of $angle BOC$ is

$110 degree$
$140 degree$
$120 degree$
$120 degree$

140 degree

angle straight A plus angle straight B plus angle straight C space equals space 180 degree

angle straight B plus angle straight C space equals space 180 degree minus angle straight A

fraction numerator angle straight B plus angle straight C over denominator 2 end fraction space equals space fraction numerator 180 degree minus angle straight A over denominator 2 end fraction space equals space fraction numerator 180 degree minus 100 degree over denominator 2 end fraction space equals space fraction numerator 80 degree over denominator 2 end fraction space equals space 40 degree

angle BOC space equals space 180 degree minus open parentheses fraction numerator angle straight B over denominator 2 end fraction plus fraction numerator angle straight C over denominator 2 end fraction close parentheses space equals space 180 degree minus 40 degree space equals space 140 degree
