You see that the tangents are

\n\"image1.jpg\"/\n\"image2.jpg\"/\n

And in case youre wondering whether the two tangents of the acute angles are always reciprocals (flips) of one another, the answer is yes.

\n

The following example shows you how to find the values of the tangent for each of the acute angles in a right triangle where the hypotenuse is 25 inches and one leg is 7 inches.

\n
    \n

  1. Find the measure of the missing leg.

    \n

    Using the Pythagorean theorem, a2 + b2 = c2, putting in 7 for a and 25 for c, and solving for the missing value, b, you find that the unknown length is 24 inches:

    \n\"image3.jpg\"/\n
    2. \n

  2. Select names for the acute angles in order to determine the opposite and adjacent designations.

    \n

    The easiest way to do this is to draw a picture and label it.

    \n\"image4.jpg\"/\n

    The two acute angles are named with the Greek letters theta and lambda. = h / 1000. Using the definition of , find the length of leg. So tan(A) = 12 / 5 and tan(B) = 5 / 12.
