    Question

    The diagonals of a rectangle are inclined to one side of

    the rectangle at 25°. The acute angle formed between the diagonals is:
    A 25° Correct Answer Incorrect Answer
    B 50° Correct Answer Incorrect Answer
    C 55° Correct Answer Incorrect Answer
    D 40° Correct Answer Incorrect Answer

    Solution

    In △BOC, ∠OBC =∠OCB ----- (Opposite angle of isosceles triangle) ∠OBC+∠OCB+∠BOC = 180 25 + 25 + ∠BOC = 180 Therefore, ∠BOC = 130 So, ∠AOB + ∠BOC = 180------- (Linear pair) ∠AOB = 180 −130 ∠AOB = 50 So, the acute angle between the diagonal is 50.
