\(\Delta\)ABCमध्ये, \(\overline {AD}\) ला दुभाजक आहे आणि D हा \(\overline {BC}\) वर एक बिंदू आहे. (\(\overline {AC}\)) = 4.2 सेमी, m (\(\overline {BD}\)) = 4 सेमी आणि m (\(\overline {BC}\)) = 7. सेमी
गणना:
DC = BC - BD = 7 - 4 = 3 सेमी
कोन दुभाजक प्रमेयानुसार:
AB : AC = BD : DC
⇒ AB : 4.2 = 4 : 3
⇒ AB = 4 × 4.2/3
⇒ AB = 5.6 सेमी
म्हणून, आवश्यक मूल्य 5.6 सेमी आहे.
