In the figure,ABCD is a rhombus.Find the values of x and y. Share with your friends Share 5 Akhil Goyal answered this We know that each side of the rhombus are equal.So, AB = BC = CD = AD.In ∆ABD, AB = AD⇒∠ADB = ∠ABD Angles opposite to equal sides are equal⇒∠ABD = xIn ∆ABD,∠ADB + ∠ABD + ∠A = 180° Angle sum property⇒x+x+80° = 180°⇒x = 50°Now, adjacent angles of rhombus are supplementary.So, ∠A + ∠D = 180°⇒80° + x + y = 180°⇒80°+50°+y = 180°⇒y = 50° 3 View Full Answer
