Which statement is true about the product of a nonzero rational number and irrational number

The product will be some (other) irrational number.

If the rational number is 1, then 1 times the irrational number is itself. Nothing changes.

If the rational number is not 1 (and also nonzero), and you multiply it with some irrational number, then the result will be some other irrational number.

Rule:

x*y = z

x is rational, y is irrational, z is irrational

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

correct answer is b. 27/8
