There is more than one way to do this, but just remember an equation is like a see saw. You need to keep it balanced. What ever you do to one side of the equation, you have to do to the other side, or you will unbalance it and the two sides will no longer be equal. I don't like having x in the denominator, so I'll start by multiplying both sides by x: Which simplifies to: So far so good. Now, I want to get rid of the tan(27°) on the left so that x is left by itself. I can divide both sides by tan(27°): Simplifying, I get: Now you can use a calculator to find an approximate value for x. Haley
