वर्गमूल सर्पिल में यदि पिछले कर्ण की लंबाई \(\sqrt{899}\) है, तो (1) इकाई लंब जोड़ने पर नया कर्ण किस सटीक मान पर होगा?
In a square root spiral, if the previous hypotenuse is \(\sqrt{899}\), at what exact value will the new hypotenuse be after adding a (1) unit perpendicular?
Explanation opens after your attempt
B. \(\sqrt{900}=30\)
Concept
The new hypotenuse is \(\sqrt{899+1}=\sqrt{900}\). Since \(900=30^2\), the exact value is (30).
Why this answer is correct
The correct answer is B. \(\sqrt{900}=30\). The new hypotenuse is \(\sqrt{899+1}=\sqrt{900}\). Since \(900=30^2\), the exact value is (30).
Exam Tip
नया कर्ण \(\sqrt{899+1}=\sqrt{900}\) होगा। \(900=30^2\), इसलिए सटीक मान (30) है।
