Find `x` and the values of `/_ AOD, /_DOC & /_BOC`

Two lines AB and CD intersect at O. If /_AOC+/_AOC+/_BOD=270^(@), find the measures of /_AOC,/_COB,/_BOD and /_DOC.

.In the adjoining figure,three coplanar lines AB , CD and EF intersect at a point O . Find the value of x . Hence, find /_AOD,/_COE and /_AOE

In the given figure DO and CO are the bisectors of /_ADC and /_BCD respectively. If /_ADC=/_BCD=60^(@) and /_DAB=100^(@) find /_DOC and /_ABC

In the given figure,O is the centre of the circle.If BD=DC and /_DBC=30^(@), find the measure of /_BAC and /_BOC.

In the following figure find the value of angle BOC .

Draw two lines bar(AB) and bar(CD) such that they intersect at point 'O' .Trace the figure given below on a tracing papier. Place the traced figure over the figure given below and rotate it such that /_DOB coincides /_COA ,Observe the angles /_AOD and /_BOC also /_COA and /_DOB .You will notice that /_AOD=/_BOC and /_CDA=/_DOB

In the given figure, AOB is a straight line and OC is a ray such that /_AOC = (3x+20)^(@) and /_BOC = (2x - 10)^(@) . Find the value of x and hence find (i) /_AOC (ii) /_BOC

In Fig. 5.53, find the value of BOC, if points A, O and B are collinear.

In then the adjoining figure,/_B=70^(@),/_C=30^(@),BD and CD are the angular bisectors of /_ABC and /_ACD then value of /_BOC

In Figure,find x .Further find /_BOC,/_COD and /_AOD
