If sin²θ = 925 and cos θ is positive, then the value of sin²θ + cos²θ is:

यदि sin²θ = 925 है और cos θ धनात्मक है, तो sin²θ + cos²θ का मान है:

Answer और ExplanationAnswer and explanation

Answer: (C) 1

sin²θ + cos²θ = 1 हर कोण (Angle) θ के लिए सत्य है; sin²θ का दिया गया मान इसे नहीं बदलता।
(जाँच: cos²θ = 1 − 925 = 1625, और 925 + 1625 = 1)
✓
मान 1 है।
sin²θ + cos²θ = 1 is true for every angle θ; the given value of sin²θ does not change it.
(Check: cos²θ = 1 − 925 = 1625, and 925 + 1625 = 1)
✓
The value is 1.
