Can someone please help me with the three questions? 12: A truck driver drove 55 miles per hour while making a delivery run. On the return trip, the driver encountered construction and her average speed reduced to just 35 miles per hour. If her total drive time was 9 hours, how long did each trip take?​

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.
