Toby is trying to show his teacher why the product of two rational numbers is another rational number. His first steps are shown. Which is the best method Toby could use to
proceed?
L
B

I think he moved forward and didn't count what he did.

Step-by-step explanation:

I just think so. It's logical reasoning, just like I was taught in math.

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.
