दिलेले आहे:

A हा कोन त्याच्या कोटिकोनापेक्षा 26° ने अधिक आहे.

B हा कोन त्याच्या पूरक कोनापेक्षा 30° ने कमी आहे.

वापरलेले सूत्र:

कोटि कोन म्हणजे ते कोन ज्यांची बेरीज 90° असते

पूरक कोन म्हणजे ते कोन ज्यांची बेरीज 180° असते

गणना:

A + A - 26 = 90

⇒ 2A = 116

⇒ A = 58

B + B + 30 = 180

⇒ 2B = 150

⇒ B = 75

म्हणून,

A - B

⇒ 58 - 75

⇒ - 17

∴ आवश्यक मूल्य - 17 आहे.
