Enter the answer in terms of fractions.
To type your equations, you can enter square root symbols, Greek letters and
subscripts by selecting the MathType popup button (red radical) in the answer box.
To enter subscripts, press the first right-facing arrow in menu of the popup. For
Greek letters, press the right-facing arrow next to the alpha (a) symbol.
Using the Pythagoroen Theorem, the third side of the 30-60-90 triangle is
sin60° = cos30º =
sin30° = cos60° =
tan30° = cot60° =
