The wheel shop sells those other kinds of vehicles there are bicycles and go karts in a different room of the shop each bicycle has only one seat each go car has only one seat there are a total of 21 seats and 54 wheels in that room how many are bicycles and how many are go karts

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.
