Download Solution PDFदिल्याप्रमाणे:
18 फूट उंच विद्युत खांबा
झाडाची उंची 6 फूट आहे.
त्यामधील अंतर 10 फूट आहे.
गणना:
आकृतीमध्ये, AB = 18 फूट , CD = 6 फूट आणि AC = 10 फूट
झाडाची सावली अशी मानूया, CO = k फूट
प्रश्नानुसार,
ΔABO आणि ΔCDO ही दोन त्रिकोण आहेत.
⇒ AB/AO = CD/CO
⇒ 18/(10 + k) = 6/k
⇒ 18k = 60 + 6k
⇒ 12k = 60
⇒ k = 5
∴ झाडाच्या सावलीची लांबी = 5 फूट
आम्ही झाडाच्या आणि विद्युत खांबाच्या मध्यभागी सावलीचा बिंदू घेऊ शकतो पण ते योग्य नाही कारण ते एकमेकांच्या विरुद्ध दिशेला आहेत असे दिलेले नाही.
