Answer:

Step-by-step explanation:

In a rectangle DC and AB are parallel.

So, alternate interior angles, ∠DCO and  ∠OAB are equal.

   ∴ ∠DCO = ∠OAB

       (X + 36)° = 68°

       X = 68 - 36

       X =  32°

As we know the in a rectangle the diagonals are equal and bisect each other.

So, AO = OB

Therefore, base angle of equal sides are also equal.

So, ∠OAB = ∠OBA

As we know that sum of all angles in a triangle =180°,

sum of all angles in ΔAOB = 180°

68° + 68° + Y° = 180°

136°+ Y° = 180°

Y° = 180° - 136°

Y° = 44°

∴   X = 32°  and  Y = 44°
