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।
