Question 32Asked in CTET February 2026 Paper 2 Maths & Science, 8 Feb 2026

If (2x − 10°) and (3x − 50°) are complementary angles, then the value of (4x + 40°) is :यदि (2x−10°) और (3x−50°) पूरक कोण हैं, तो (4x+40°) का मान है :

यदि (2x−10°) और (3x−50°) पूरक कोण हैं, तो (4x+40°) का मान है :
  1. A160°160°
  2. B180°180°
  3. C120°120°
  4. D150°150°
Show answerHide answer

Correct answer: (A) 160°160°

Explanation

(2x − 10) + (3x − 50) = 90 gives 5x = 150, x = 30. Then 4x + 40 = 120 + 40 = 160°.(2x − 10) + (3x − 50) = 90 से 5x = 150, x = 30। तब 4x + 40 = 120 + 40 = 160°।
