A) 100 degrees (congruent angle)
B) 45 degrees (congruent angle)
C) 90 degrees (right angle)
D) 99 degrees (congruent angle)
E) 30 degrees (congruent angle)
F) 30 degrees (180-150=30, that is to find the other angle that is congruent to f)
dot on top of earth = plane position at the time of observation (right one when 37°, left one 53°)
then the geometry is zoomed on the left side
2 x (5-2)^3
2 x (3)^3
2 x 27

There are 11 full tables, because when you divide 138 by 12 you get 11 remainder 6. So there is 11, because 12 people are at 11 tables and 6 at one!
