So me and my office mate Bill Baer were talking about his trip to Shell Oil in the Netherlands. He will be flying First Class and how the seats recline to *almost* 180 degrees.
Bill: I wonder how close to 180 it gets. Maybe I should bring my protractor.
Me: LOL! Wait…We could figure it out. Use trig.
Me: Let’s see…<I start drawing on the whiteboard> If we measure the length of the back of the seat from the top to the floor and then measure the total length of the seat….
Bill: ahhhh. And use the X^2 + Y^2 thing?
Me: well…we will already know the lengths (sides) so what we want to know is the angle, so the sine of theta (the angle we want to know) would be the length of the opposite side divided by the hypotenuse of the triangle it makes. Or even better, the tangent of the angle would be the length of the opposite side divided by the length of the seat.
Bill: nice. Let me get my ruler. <He prints out a ruler>
