In the Triangle ABC, BE is perpendicular to AC, Angle EBC is 40 and Angle DAC is 30, find the values of x,y,z. Share with your friends Share 11 Lovina Kansal answered this Dear student In △EBC, by angle sum property of triangle∠EBC+∠ECB+∠BEC=18040+x+90=180x=50Let the point where BE and AD intersect be O.In △AOE, by angle sum property of triangle∠AEO+∠EAO+∠AOE=180°⇒90°+30°+∠AOE=180°⇒∠AOE=60°Since BE is a straight line,Therefore,z+∠AOE=180° (Linear pair)⇒z=180°-60°⇒z=120°Since AD is a straight line,Therefore,z+∠BOD=180° (Linear pair)⇒∠BOD=180°-120°⇒∠BOD=60°In △BOD, by angle sum property of triangle∠BOD+∠DBO+y=180°⇒60°+40°+y=180°⇒y=80° Regards 4 View Full Answer Harshita Yadav answered this Easy... X=50 ,Y=80, Z=120 1 Kesha Parsania answered this how did u get y=120 ? plz show step by step .... I was kinda confused with 'y' 0
