Sylvias mixing concrete for her patio for every 26.7 pounds of concrete mix she needs to add 1 quart of water Sylvie buys 80 kg of concrete mix how many quarts of water rounded to the nearest 10th is so we need to add 80 kg of concrete mix

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.
