Detailed Solution
Download Solution PDFপ্রদত্ত:
কোণ PQR = 90° এবং QS ⊥ PR
PQ = 6 সেমি এবং PS = 4 সেমি
অনুসৃত ধারণা:
সমকোণী ত্রিভুজে,
অতিভুজ2 = ভূমি2 + লম্ব2
গণনা:
ত্রিভুজ PQR এ = 90° এবং QS ⊥ PR
∴ QSP = 90°
QSP এ পিথাগোরাসের উপপাদ্য প্রয়োগ করার পর
QS2 + SP2 = QP2
⇒ x2 + 42 = 62
⇒ x2 = 36 - 16
⇒ x = √ 20
⇒ x = 2√ 5
∴ বিকল্প 1 হল সঠিক উত্তর।
