Download Solution PDFপ্রদত্ত:
একটি সামন্তরিকের শীর্ষবিন্দু = (-5, 5); (x, 10); (10, 6); (-2, 1)
ধারণা:
একটি সামন্তরিকের কর্ণ পরস্পরকে দ্বিখণ্ডিত করে।
অনুসৃত সূত্র:
মধ্যবিন্দু = \((\frac{x_1\ +\ x_2}{2},\ \frac{y_1\ +\ y_2}{2})\)
গণনা:
এখানে, O হল AC এবং BD-এর মধ্যবিন্দু কারণ একটি সামন্তরিকের কর্ণ পরস্পরকে দ্বিখণ্ডিত করে।
এখন, AC-এর মধ্যবিন্দু = BD-এর মধ্যবিন্দু
⇒\(\frac{-\ 5\ +\ 10}{2}\ =\ \ \frac{x\ +\ (-\ 2)}{2}\)
⇒ 5 = x - 2
⇒ x = 7
∴ x এর মান 7
