Sis the centroid of triangle xyz. what is the length of sw? 5 units 11 units 22 units 28 units

The answers are 20,30,80,180,960,890,1230,4560. on the first row

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
