Extracted text: в (5,3,2) Х axis (1,1,5) A (5,-3,2). Z axis ! Y axis o (0,0,0) Look at figure 1 carefuy. Your task is to determine the position of the shadow of the blue ball at (1,1,5) on the surface of the orange block. The positions of the three vertices of the surface, point A, point B, and point O are given in the figure, along with the direction of the three axes. The direction of the sun-rays is given by the vector d=<1,0,-2.55». la)="" what="" is="" the="" angle="" (in="" degree)="" between="" the="" sun-ray="" vector="" d="" and="" the="" vector="" oa→="">
