The water level in ricky lake changes of -9/20 inch every 3 years
based on the rate above how much will the water level change after one year? show your calculations and model your answer on the vertical number line, using 0 as the original water level

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

step-by-step explanation:

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.
