Please help me solve this

Problem 4 (20 points) We have the following three subspaces of R. Note that V is also a subspace of W. U = Span { [1, 1, 0]), V = Span{ [1, -1, 0]), W = Span { [1, 0, 1], [0, 1, 1]} 1. For those that are defined, find the bases and dimensions of the direct sums U O V, U O W, and V O W. 2. Explain whether each of the pairs U and V, U and W, and V and W are complementary subspaces with respect to RS. 3. What are the dimensions of the annihilators of U, V, and W? 4. Find three different homogeneous linear systems whose solution sets are U, V, and W, respectively
