Winder stairs are sometimes used to construct 90 degree turns within a staircase especially in older homes, since they take up less space than a staircase with a landing. Two of the three pictured treads are congruent right triangles, and the other is a kite. All three treads have 30 degree angles at the center of the turn. 30 18 30" What is the total area of all three treads? * Your answer What is the measure of each obtuse angle on the kite-shaped stair tread? *
