Rainbow candy rainbow candy:
∵∠ACB=60°,∠ABC=50°
Bo and Co are bisectors of ∠ ABC and ∠ ACB respectively
∴∠OBC=1/2∠ABC=25°,∠OCB=1/2∠ACB=30°
And ∵ EF passes through o point and is parallel to BC
∴∠EOB=∠OBC=25°,∠FOC=∠OCB=30°
EOF is a flat angle, i.e. 180 degree
∴∠BOC=180°-∠EOB-∠FOC=180°-25°-30°=125°
∴∠BOC=125°
