More Foldable!

Flip your foldable over to the backside (the only part left blank) and add these titles to each box: next, draw this example triangle and set up the sin ratio: and then solve for theta using inverse sin or acrsin:
then draw this example triangle and set up the cos ratio:

 and solve for theta using inverse cos or arccos:

Lastly, let's do the same for tangent, start with the example triangle and set up the tangent ratio: then solve for theta using inverse tan or arctan:

When you're all done it should look like this: or like this:
