यदि (7) नए चरण बनाने के बाद कर्ण \(\sqrt{29}\) मिला, तो शुरुआत में कौन सा कर्ण था?
If after (7) new steps the hypotenuse becomes \(\sqrt{29}\), what was the starting hypotenuse?
Explanation opens after your attempt
C. \(\sqrt{22}\)
Concept
Going (7) steps backward gives (29-7=22). Therefore, the starting hypotenuse was \(\sqrt{22}\).
Why this answer is correct
The correct answer is C. \(\sqrt{22}\). Going (7) steps backward gives (29-7=22). Therefore, the starting hypotenuse was \(\sqrt{22}\).
Exam Tip
(7) चरण पीछे जाने पर (29-7=22) मिलता है। इसलिए शुरुआत का कर्ण \(\sqrt{22}\) था।
