Kelsey is looking for a repair service for general household maintenance. One service charges $75 tojoin the service and $30 per hour. Another service charges $45 per hour and no fee for joining the service. After how many hours of service is the total cost for the two services the same?​

true

explanation:

i believe the answer is the polygon, heptagon.

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.
