Anyone explain on what to do?
sabah has $450 to pay for college textbooks. she expects to pay about $75 per book. her friend told her that 4 of them can be checked out of the library for free.
complete the equation below to find the total number of books that sabah can get for her classes. use b to represent the total books.

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.
