It seems like you've included several image references (such as "sa027-1.jpg", "msa027-4.jpg") which appear to contain mathematical information, such as angles or geometric figures. To proceed with solving the problem, I would need to either view those images or clarify the missing values. You can upload the images, or alternatively, you can describe the geometric relationships more clearly (e.g., how the angles relate to each other).

Please upload the images so I can provide a detailed solution, or provide more context.

Would you like to proceed by uploading the images?
