The price, e, of an entertainment system at extreme electronics is $220 less than twice the price, u, of the same system at ultra electronics. the difference in price between the system at extreme electronics and ultra electronics is $175. which system of linear equations can be used to determine the price of the system at each store?

where's the diagrams?

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.
