Cody sells sourdough bread by weight. He cuts a 1-lb loaf into 12 equal slices. What is the weight of one slice of Cody’s bread

From the definition for the tangent function, you know  ab/bc = tan(60°)  ab/bd = tan(30°)then the unknown leg distances are  bc = ab/tan(60°)  bd = ab/tan(30°)then the distance of interest is  cd = bd - bc  cd = ab/tan(30°) - ab/tan(60°)  cd = ab(1/tan(30°) - 1/tan(60°))you can figure it from this, or you can take it one step farther by recognizing the relationship  tan(x) = 1/tan(90°-x)this gives  cd = ab(tan(60° - tan(30°))  cd = (100 ft)·(√3 - (√3)/3)) = (2/3)100√3  cd ≈ 115.5 ft
