We know that AE is a transversal since AB DE
Here BAC and AED are alternate interior angles.
Hence, BAC = AED
It is given that BAC = 35°
AED = 35°
Now consider the triangle CDE. We know that the sum of the interior angles of a triangle is 180°.
∴ DCE + CED + CDE = 180°
Putting the values, we get
DCE + 35° + 53° = 180°
Hence, DCE = 92°
