Answer:
D. tan50° = 3/a
Step-by-step explanation:
We use tangent (tan∅) to find <em>a</em>. Remember tan is opposite over adjacent.
y = k/x, where k is the variation constant.
We need to find k.
5 = k/15...This equation leads to the correct value of k (our variation constant).
5(15) = (k/15)(15)
75 = k
Done!
