दिया है: एक 12 घंटे की घड़ी जब समय 9 : 25 हो रहा है।

प्रयुक्त सूत्र:

मिनट की सुई और घंटे की सुई के बीच का कोण = \({(60 \:H - 11\:M)\over 2}\)

जहाँ H घंटे का प्रतिनिधित्व करता है और M मिनटों का प्रतिनिधित्व करता है।

गणना:

मिनट की सुई और घंटे की सुई के बीच का कोण = \({(60 \:H - 11\:M)\over 2}\)

मिनट की सुई और घंटे की सुई के बीच का कोण = \({265\over 2} = 132.5^\circ\)

इस प्रकार, मिनट की सुई और घंटे की सुई के बीच का सन्निकट कोण '130°' है।
