Line F.B B.B
AB 188$^\circ$45' 7$^\circ$45'
BC 118$^\circ$15' 298$^\circ$15'
CD 346$^\circ$35' 166$^\circ$30'
DE 337$^\circ$05' 158$^\circ$10'
EA 293$^\circ$30' 113$^\circ$00'

To find the correct including angle

enter image description here

$\angle$A = F.B of AB – B.B of EA = 188$^\circ$45’ - 113$^\circ$00’= 75$^\circ$45’

$\angle$B = F.B of BC – B.B of AB = 118$^\circ$15’- 7$^\circ$45’= …
