`ED ||AC angle CBE = 65^(@) angle DEC = ?`

In figure chord ED is parallel to the diameter. AC of the circle. If angle CBE = 65^(@) then angle DEC = ?

In a quadrilateral ABCD, E is a point in the interior of the quadrilateral such that DE and CE are the bisector of angle D and angle C , respectively, If angle B = 82^@ and angle DEC = 80^@ then angle A = ? एक चतुर्भुज ABCD में, E, चतुर्भुज के भीतरी भाग का एक बिंदु इस प्रकार है की DE और CE क्रमश angle D और angle C , के द्विभाजक हैं, यदि angle B = 82^@ और angle DEC = 80^@ तो angle A = ?

AB is diameter angle ABC = 65^(@) angle CAD = 45^(@) angle DCA =

In the figure given below, AB is parallel to CD, angle ABC = 65^@, angle CDE = 15^@ and AB = AE . What is the value of angle AEF ?

If the given figure, AB is diameter of the circle, C and D lie on the semicircle. angle ABC = 65^(@) and angle CAD = 45^(@) , find angle DCA .

In Delta ABC BC bot AC at D.E is a point on BC such that angle BEA = x^(@) If angle EAC = 36^(@) and angle EBD = 40^(@) , then the value of x is:

In the following figures, AB be diameter of a circle whose centre is O. If angle AOE = 150^(@), angle DAO = 51^(@) , then the measure of angle CBE is-

In a Delta ABC, angle A=65^(@), angle C=75^(@) , where O is circumcentre , find angle OAC .
