Show answer & explanation
Correct answer: B
Let the given acute angle be x.
Complementary angle = 90° - x
Supplementary angle = 180° - x
Difference = (180° - x) - (90° - x) = 180° - x - 90° + x = 90°
Thus, the difference between the supplementary and complementary angles of any acute angle is always 90°.
हिन्दी उत्तर:
माना दिया गया न्यूनकोण x है।
पूरक कोण = 90° - x
सम्पूरक कोण = 180° - x
अंतर = (180° - x) - (90° - x) = 180° - x - 90° + x = 90°
इसलिए, किसी भी न्यूनकोण के सम्पूरक और पूरक कोणों का अंतर हमेशा 90° होता है।
