For questions 1-3, use the triangle below. 1. Find the length of side b to two decimal places.
2. Find the length of side a to two decimal places.
3. Find sin55° using ratios of sides of this triangle; check using your calculator.

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?
