1.	31. In the given figure BO and CO are bisectors of angle DBC and angle ECB respectively. Ifangle BAC = 70° and angle ABC = 40°. Find the measure of angle BOC.
Answer» ANSWER: it seems to be a rhombus therefore SUM of OPPOSITE ANGLES are supplementary therefore angle A + angle O=180 70+angleO=180 angleO=180-70 angleO=110

Answer»

ANSWER:

it seems to be a rhombus

therefore SUM of OPPOSITE ANGLES are supplementary

therefore angle A + angle O=180

70+angleO=180

angleO=180-70

angleO=110
