\(\Delta\)ABC में, \(\overline {AD}\) \(\angle\)A को समद्विविभजित करता है और D \(\overline {BC}\) पर एक बिंदु है। यदि m (\(\overline {AC}\)) = 4.2 सेमी, m (\(\overline {BD}\)) = 4 सेमी और m (\(\overline {BC}\)) = 7 सेमी है।
गणना:
DC = BC - BD = 7 - 4 = 3 सेमी
कोण द्विभाजक प्रमेय के अनुसार:
AB : AC = BD : DC
⇒ AB : 4.2 = 4 : 3
⇒ AB = 4 × 4.2/3
⇒ AB = 5.6 cm
अतः अभीष्ट मान 5.6 सेमी है।
