Question

In the given figure, AB is parallel to CD.

Angle ABO is 60 degrees and angle DCO is 40 degrees Find angle BOC

Answer 1

Answer:

Answer:

BOD=10

Step-by-step explanation:  Let f be intersection of AB and BO

consider the Δ FOD then OFD=ABO=40

and FDO=180-CDO⇒FDO=180-50=130

Therefore BOD=180-DFO-FDO⇒BOD=180-(40+130)=10

Step-by-step explanation:

Answer 2

Answer:

Answer:

BOD=10

Step-by-step explanation:  Let f be intersection of AB and BO

consider the Δ FOD then OFD=ABO=40

and FDO=180-CDO⇒FDO=180-50=130

Therefore BOD=180-DFO-FDO⇒BOD=180-(40+130)=10
