चित्र 9.43 में यदि `"EC || AB"` तथा `angleECD = 70^(@)` व `angleBDO = 20^(@)` हो, तो `angleOBD` =

In the given figure, if EC || AB, angle ECD = 70^(@), angle BDO =20^(@) , then angle OBD is

In fig. if EC||AB, angleECD=70^@ and angleBOC=20^@ then angleOBD is

In the figure given above EC is parallel to AB, angleECD = 70^(@) and angleBDO = 20^(@) . What is angleOBD equal to ?

In the figure given below, EC is parallel to AB, angleECD = 70^@ and angle BDO = 20^@ . What is the value of angleOBD

In the triangle, if AB=AC and angle ABC = 72^@ , then angle BAC is: एक त्रिभुज में, यदि AB=AC तथा angle ABC = 72^@ है, तो कोण BAC का मान क्या होगा ?

In triangle ABC , if AB=AC and angle BAC= 40^@ ,then the measure of angle B is त्रिभुज ABC में, यदि AB=AC है तथा angle BAC= 40^@ है, तो कोण B का मान क्या होगा ?

In triangle ABC , D is a point on AC such that AB = BD = DC. If angle BAD=70^@ , then the measure of angle B is: त्रिभुज ABC में, D एक ऐसा बिंदु है कि AB = BD = DC है । यदि angle BAD=70^@ है, तो कोण B का मान ज्ञात करें |
