Answer:
10 & 11 are 29 and 151. 9 is vertical to 10, so it must also be 29 as defined by the first angle. 12 is supplementary to 13, so it must be the difference of 180 by 65: 115. 4 is part of a right triangle, so it must be 45. 7 is vertical to 4 and 3, so adding those angles together will be 70 degrees. By defining what 7 was we now can figure out what 6 is, angle 1 & 7 add up to 99, subtract that from 180 (b/c they're on a flat line.) You recieve 81. Finally angle 8 is supplementary from 9, stating it must be 151. (Oh yea, 14 & 15 are 115 & 65.) Sorry this took so long.
