Step 3: Identify the side length to solve for, noting whether it is the opposite or adjacent side relative to the angle from Step 2. Beat app, calculates everything perfectly. Side I G is eight units. Because tangent is the ratio between opposite and adjacent sides, {eq}\tan \hat{C} = \displaystyle \frac{c}{b}. Triangle LMN and MNO are similar as they're both 30-60-90 triangles, so we can set up the proportion LM/MN = MN/NO or 163/16 = 16/x. Recall that the tangentof an angle is the ratio of theoppositeside to theadjacent sideof that triangle. Log in here for access. Therefore. If you look at the sine, cosine and tangent graphs, you'll see that they go on forever. Now, take the decimal portion in order to find the number of inches involved. 165.
