यदि \(OP=\sqrt{20}\) है, तो इससे ठीक पहले बने कर्ण की लंबाई क्या थी?
If \(OP=\sqrt{20}\), what was the length of the hypotenuse formed just before it?
Explanation opens after your attempt
B. \(\sqrt{19}\)
Concept
In the immediately previous step, the number under the root is (1) less, so the length is \(\sqrt{19}\). Learn to read the sequence backward too.
Why this answer is correct
The correct answer is B. \(\sqrt{19}\). In the immediately previous step, the number under the root is (1) less, so the length is \(\sqrt{19}\). Learn to read the sequence backward too.
Exam Tip
ठीक पहले वाले चरण में वर्गमूल के अंदर की संख्या (1) कम होगी, इसलिए लंबाई \(\sqrt{19}\) है। क्रम को पीछे से पढ़ना भी सीखें।
