Incidentally, you can still proceed by contradiction. Suppose A ⊆ C and B ⊆ C, but somehow A ∪ B ⊈ C. Then there must be an element x ∈ A ∪ B such that x ∉ C. There are two possibilities: either x ∈ A or x ∈ B (or both are true). If x ∈ A, then x ∈ C, by the premise. But if x ∈ B, then also x ∈ C, again by premise.
