Elementary MathematicsTrigonometry
- A√2-1
- B√2+1
- C√3-1
- D√3+2
Explanation
The trigonometric equation in the stem could not be recovered (options sqrt(2)-1, sqrt(2)+1, sqrt(3)-1, sqrt(3)+2). The key is taken from the published coaching key (PW, CDS 2 2025 Set A: A, i.e. sqrt(2)-1). Note: key disputed - independent verification inconclusive.
