Answer will be 110 degree.
Because angle CBD= angle ACB. [alternate interior angles]
therefore, angle ACB=40degree.
Angle ABC = angle CAB. [angles opposite to equal sides of a triangle are equal]
Now taking angle ABC = angle CAB =Y
Then, Y+Y+40 degree = 180 degree.
therefore, Y=70 degree.
Now, 70 degree +40 degree = X [exterior angle of a triangle is equal to the sum of the two remote angles]
Therefore, X=110 degree.
