Question

in the given figure,AB parallelCD, angle ABO=40 degree and angle CDO =50 degree, then find the value of angle BOD.

Answer 1

Answer:

BOD=10

Step-by-step explanation: let f be the point of intersetion of BO and AD

so AFO=ABO beacause AB // TO CD then let's consider the Δ AFO

FDO=180-ADO=180-50

FDO=130

THEREFORE FOD=BOD=180-DFO-FDO

FOD=180-(40+130)=10
