Designing a Chair! By: Ryan Broadwater, Tasha Gordon, Emmet Boettner

We had used cosine to find the lengths for the legs of the chair. We kept the base of the chair a "30, 60, 90" triangle. The distance we wanted the legs of the chair on the ground to be 3 feet apart, which was the hypotenuse of the triangular base. Using cos=opp/hyp, or in this case cos(30)=x/3 we found the one leg to be 2.6 feet long. Then using the same formula we plugged in cos(60)=x/3 we found the other leg to be 1.5 feet long. Then for the back rest and actual part you sit on we used realistic lengths. We thought the back rest should be 3 feet long and the "sitting" part should be 1.25 feet long.
