Answer:
tan 58° = 11/x
Explanation:
The two legs form the right angle of the triangle.
One leg is x, and the other leg is 11.
Look at the 58° angle. The leg with length x is next to the 58° angle, so the leg with length x is the "adjacent" leg. The leg with length 11 is opposite the 58° angle, so that leg is the "opposite" leg. For the 58° angle, adj = x, and opp = 11.
Now you need to remember the definitions of the sine, cosine, and tangent ratios for a right triangle.
sin A = opp/hyp
cos A = adj/hyp
tan A = opp/adj
The only ratio that involves the adjacent and opposite legs is the tangent.
