Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिया गया है:
BC = 16 cm, BD = 11 cm और ∠ADC = ∠BAC
संकल्पना:
यदि दो त्रिभुजों के दो कोण और एक भुजा बराबर हों, तो दोनों त्रिभुज समरूप होंगे।
गणना:
ΔABC और ΔADC में
⇒ ∠ADC = ∠BAC
⇒ ∠C = दोनों त्रिभुजों में उभयनिष्ठ कोण
⇒ AC = उभयनिष्ठ भुजा
इसलिए, ΔABC और ΔADC समरूप त्रिभुज हैं।
⇒ \({BC\over AC}={AC\over DC}\)
⇒ AC2 = BC × DC
⇒ AC2 = 16 × 5 = 80
⇒ AC = 4√5
∴ अभीष्ट परिणाम 4√5 होगा।
