You are skiing down a mountain with a vertical height of 1100 feet. The distance from the top of the mountain to the base is 2200 feet. What is the angle of elevation from the base to the top of the mountain?

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?
