In the figure, if AB ││CD, then find the value of ‘x’. Share with your friends Share 1 Anuradha Sharma answered this Join AC, So we get ∠BAC=∠DCA=90 degreeSo now ∠EAC = 110-90= 20 degreeNow in triangle ACE, ∠ACE = 180-∠EAC -∠AEC=180-20-25 = 135 degreeSo Now sum of all the angles around C will be 360 degree and hence90+135+x = 360 x = 135 degree 9 View Full Answer Susovan Roy answered this I THINK THE ANSWER IS 135O . THANK YOU. 3
