In the half of plane which includes ray OA, we have 
 so the ray OC is between two rays OA and OB, hence 
Thus, 
0.25

b
Because the ray OD is opposite ray of OB, angle BOD is straight angle. Hence angle AOD and angle AOB are adjacent – supplemetary angles. We have
Thus, 
0.25
0.25
0.25
c
We see two angles BOC and DOC are two adjacent- supplementary angles so 
Hence, 
Thus, the ray OA is bisector of angle COD.

Since Samuel gave the same number of strawberries to each friend then we have:
150 : 5 = 30
Thus, Each friend of Samuel received 30 strawberries.
