Answer:
tan 38 = 0.781
Explanation:
Tan is a short form of tangent. from trigonometry whenever we are given a right angle triangle the tangent is adjacent side divided by the opposite side of the triangle. tan 38° is constant you can check a four figure table.
see below
sine = opposite / hypothenus
Cosine = adjacent / hypothenus
Tangent = opposite / adjacent
Tan 38° is a simply the ratio of the opposite side of the angle 38° to the side adjacent to the angle given that the angle 38° is constant.
mathematically,
tan 38° = opposite/ adjacent
0.781 = opposite/ adjacent
