A train consisting of 50 cars and one locomotive weighs a total of 4,725 tons. The locomotive weighs 125 tons. All of the cars have the same weight. Find the weight (in tons) of one car.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

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.
