BA = ( 34 - 15 ) + 5,6 / 2 = 21,8 m
BE = ( 34 - 15 ) - 5,6 / 2 = 16,2 m
tan ( BOE ) = BE / BO = 16,2 / 22 = 0,73636...
BOE = arc tangente de 0,736... = 36° 21' 59,689"
tan ( BOA ) = BA / BO = 21,8 / 22 = 0,9909090...
BOA = arc tangente de 0,990... = 44° 44' 18,158"
angle EOA = BOA - BOE = 8° 22' 18,469"
