दिया गया है:

एक कोण का संपूरक इसके पूरक के तीन गुने से 15° अधिक है।

प्रयुक्त सूत्र:

इस प्रकार के प्रश्न में, कोण का संपूरक = 180° – x,

कोण का पूरक = 90° – x

गणना:

माना कि कोण x° है

प्रश्न के अनुसार,

180° – x = 3(90° – x) + 15°

⇒ 180° – x° = 270° – 3x° + 15°

⇒ 2x = 105

⇒ x = 52.5

∴ कोण का माप 52.5° है।
