Four angles of a pentagon are equal and the fifth is 60°.find the equal angles and show that two sides of the pentagon are parallel.
i have found the angles and i just want to know how to show that two sides are parallel. do i draw the irregular pentagon? if so, how?

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?
