The number of gallons of water in a leaking pool is determined by the rate that the water is filling, 8g^2 + 3g– 4, and the rate that water leaks from the pool 9g^2– 2g- 5, where g, represents the number
of gallons entering or leaving the pool per minute.

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.
