Can someone please tell me step by step how to do equations like this? A quadrilateral (rhombus) or any other quadrilateral for that fact has 2 angles were you need to find the measures. The angle equations are something like (x+38) and (4x-1). How would I solve it?

Thelime contains the point(-3,0) and parallel x-3y=3( show all work)

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
