given that
AC || BD and BC piercing
BC = AC
ANSWER
AC || BD and BC piercing so ,
angle CBD = angle ACB
angle ACB = 40°
angle CBD = 40°
BC = AC so, angle CBA = angle CAB
we know that the sum of three angle of a triangle is 180°
angle ACB+angle CBA+angle CAB = 180
=> angle ACB+angle CAB+angle CAB = 180
=> 40+2angle CAB = 180
=> 2angle CAB = 140
=> angle CAB = 70
BE straight line so angle EAB = 180
angle EAB = angle CAE+angle CAB
=> 180= x+70
=> x = 180-70
=> x = 110
