I don’t understand why the answers are in reverse of my choices. Shouldn’t the third length be larger than (4 + 7=) 11?
Smaller, not larger. Revisit this on PrepSwift.
Ahhh got it! Just re-watched the Possible Side Lengths of Triangle. To answer this question, we have to form a range
4 + x > 7
4 + 7 > x
Solving for the range
x > 3
x < 11
Therefore the range is 4 - 10
