Answer:
50°
Step-by-step explanation:
In a rectangle ABCD,
⇒ ∠ACD = 25°
⇒ ∠CAB = 25°
⇒ ∠BCA = 90° - 25° = 65° = ∠DAC
Now,
In rectangle, diagonals bisect each other.
OD = OB and OA = OC
So, ΔODC and ΔOAB are congruent.
∠OBA = 25° = ∠DCA
Now, ∠AOD is exterior angle of ΔAOB
⇒ ∠AOD = ∠OAB + ∠OBA
= 25° + 25°
= 50°
Therefore,
Acute angle between the diagonals = 50°
Hope it helps!
