∠A and \angle B∠B are supplementary angles. If m\angle A=(7x+3)}∠A=(7x+3) ∘ and m\angle B=(7x+23}∠B=(7x+23) ∘ , then find the measure of \angle A∠A.

Brook states that the distance on the line is 4 units. caleb states that the whole line does not have a distance because it continues on forever. vivian states that the line is 6 units long. which distance did brook measure? which distance did vivian measure?
