B (5,3,2) X axis (1,1,5) A (5,-3,2) Z axis Y axis O (0,0,0) Look at figure I carfuy. Your task is to deternine the position of the shadow of the blue ball a (,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 axe. The direction of the sun-rays is given by the vector d=<1,0,-2.5>. la) What is the angle (in degree) between the sun-ray vector d and the vector OA→ ?
