Math 10 Lesson 7–1 Trigonometry – tangent, sine, cosine
put into a table like the one on the right so that people could look up the ratio and the angle that corresponded to that ratio Fortunately for us we can use a calculator to find (a) the angles that correspond to a ratio and (b) to calculate the tangent from the angle From the example above we calculated tan F = 1 591 and tan G = 0 6286

Pass out copies of the tangent table (pg 7) Look up the angle you measured with the astrolabe in the table and write its tangent on your data sheet Explain: The tangent is the ratio between the opposite and adjacent sides of any right triangle containing this angle —in this case, the flagpole and the baseline
