∠A and \angle B∠B are complementary angles. If m\angle A=(x+10)^{\circ}∠A=(x+10) ∘ and m\angle B=(3x+28)^{\circ}∠B=(3x+28) ∘ , then find the measure of \angle B∠B

This would be an open primary. a closed primary people can vote only prior to election day if the party if they are registered. independent voters can not participate. there is not a wide-open primary, but there is a semi-open primary.

None   they are   equally likely to occur on any plate boundary
