First, let's expand the right side. Now our equation is

Now, we gather all the terms with x in it on the left side, and the numbers without x on the right. We get:

And then we can make this

We divide both sides by 12 to get x on its own, so x = 13/12 or 1.08
If you put it into your calculator by pressing the COS button and then typing in 105, you get -0.258819045...
So 3/10 green and 1/5 blue. First, let's convert them into equal fractions. Now we have 3/10 and 2/10. When combined, it is 5/10. That means there is a 50% chance you will land on blue or green.
