Hi, there-- You need to give more information here. I suspect that you have a drawing as part of this problem. You would need to describe it so that we know how angle 1 and angle 2 relate to angle WOY and angle ZOX. (You can also provide a link to the drawing if you have one.) Repost here, or email me directly, Mrs. Figgy math.in.the.vortex@gmail.com
