15. Ocean waves move in parallel lines toward the shore. The figure shows the path that a windsurfer takes across
several waves. For this exercise, think of the windsurfer's
wake as a line. If m<1= (2x + 2y)° and m<2= (2x + y)º
find x and y. Explain your reasoning.
70°

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- 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. 3- 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 part b?
