Question 41Asked in CTET February 2026 Paper 2 Maths & Science, 7 Feb 2026

If (3x − 30°) and (2x + 20°) are two supplementary angles, then the value of (2x − 4°) is :यदि (3x − 30°) और (2x + 20°) दो संपूरक कोण हैं, तो (2x − 4°) का मान है :

यदि (3x − 30°) और (2x + 20°) दो संपूरक कोण हैं, तो (2x − 4°) का मान है :
  1. A72°72°
  2. B76°76°
  3. C80°80°
  4. D84°84°
Show answerHide answer

Correct answer: (A) 72°72°

Explanation

(3x − 30) + (2x + 20) = 180 gives 5x = 190, so x = 38 and 2x − 4 = 72°.(3x − 30) + (2x + 20) = 180 से 5x = 190, इसलिए x = 38 और 2x − 4 = 72°।
