File 36 54 90 Triangle Svg Wikimedia Commons It's a right triangle, so that makes it easier The short side is opposite the small angle, 15 , so 5 = hyp*sin (15) hyp = 5/sin (15) =Special Right Triangle Apply your sidechasing skills and the angle sum rectangle above to find the exact lengths of the missing triangle side lengths below Based on this, devise a Special Right Triangle rule Side lengths of a 15 75 90 triangle
First, the constant function satisfies the property of being of degree ≤2 Next, it clearly interpolates the given data Therefore by the uniqueness of quadratic interpolation, P2(x) must be the constant function 1 Consider now the data points (x0,mx0),(x1,mx1),(x2,mx2)
