Copy of Exploring cosine in a 30,60,90 triangle

Exploring the relationship between the adjacent length and the hypotenuse in a 30,60,90 triangle.
Make a table to record a range of sizes. You columns should be:[br][list][br][*]hypotenuse length[br][*]adjacent length[br][*]adjacent/hypotenuse[br][/list]
