In ΔXYZ, x = 940 cm, ∠Y=139° and ∠Z=20°. Find the length of z, to the nearest centimeter.

What is the value of x in the following equation. -x ^3/2 = -27

Which expression converts 45 degree to radians

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?
