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?

X+y=-4 x-y=2 use elimination with adding and subtraction

Plz ( true - false) all triangles have interior angles whose measure sum to 90.
