I think there's something wrong here. As the angles formed by the diagonals of a rectangle and the length are equal, angle FAB should be 37 degrees and, as angle FAB isn't 0, the answer is obviously 53 degrees, but it's been set to 37 degrees for reasons beyond my comprehension.

Class : Class 10

Ans 7:

Prabodh Shejwalkar from Aksharnandan Secondary School, Pune

To solve: (2 5/4 - 5 1/6 + 3 1/3) / (0.087 + 0.3717 ÷ 0.9) Step 1: Simplify the Numerator Convert each mixed number to an improper fraction: 2 5/4 = 13/4 5 1/6 = 31/6 3 1/3 = 10/3 Rewrite the expression as: 13/4 - 31/6 + 10/3 Find a common denominator (12) and convert: 13/4 = 39/12 31/6 = 62/12 10/3 = 40/12 Now calculate: 39/12 - 62/12 + 40/12 = 17/12 Step 2: Simplify the Denominator The denominator is: 0.087 + 0.3717 ÷ 0.9 First, perform the division: 0.3717 ÷ 0.9 = 0.413 Then add 0.087: 0.087 + 0.413 = 0.5 Step 3: Divide the Numerator by the Denominator Now we have: (17/12) ÷ 0.5 = (17/12) × 2 = 34/12 = 2.833 Answer: The correct answer is A. 2.833 The questions are a bit tricky, you just need to use your brain and stop blaming SOF.
