Question

In the diagram given below, find the value of x. If angle AOB 45 , angle AOD 170 and the chords AB and CD are equal​

Answer 1

Answer:

Consider triangle AOB and triangle OCD

OA=OB=OC=OD=radius

∠AOB=∠DOC=70

In △OCD

OD=OC

∠ODC=∠OCD

∠OCD+∠ODC+∠DOC=180

2∠OCD=180

o

−70

o

∠OCD=55

o

=∠ODC
