![Definition: A space X is compact provided that every open cover of X has a finite
subcover. Equivalently, X is compact provided that for every collection O of open
sets whose union equals X, there is a finite subcollection {O;}\1 of O whose union
equals X. A subspace A of a space X is compact provided that A is a compact
topological space in its subspace topology.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa279d709-2503-4944-8ec2-0472e9533efc%2Fd15d2635-dd98-426d-ba83-f356a643277c%2Fodg9j7p_processed.jpeg&w=3840&q=75)
