Sir question 5 bahut easy hai In ∆OXR - using Pythagoras theorem (OR)² = (OX)² +(RX)² (5)² =(x)²+(RX)² 25 - x²= (RX)². -----(1) In ∆RXS‚ using Pythagoras theorem (RS)² = (XS)² + (RX)² (6)²= (5- x)² + (RX)² 36 -(25 + x² -10x) = (RX)² 36-25-x²+10x =(RX)² 11-x²+19x = (RX)². ------(2) From eq 1&2 25 - x²= 11- x² +10x 25-11 = 10x x = 1•4x From eq(1) 25-x² = (RX)² 25 - (1•4)² = (RX)² 25 - 1•96 = (RX)² (RX)² = 23•04 RX = ✓23.04 RX = 4.8m RX = 2×RX 2 ×4•8 9•6m answer 👍👍

Hey can you please tell me how after opening 6²= (5-x)²+(Rx)² We got 36=25+x² -10x=(Rx)² Instead of 36=25+x²=(Rx)²

[@AdityaPatel-d5k]

@@sukhadeokhandare-gy6zq are bhai 6² ka 6×6 karoge to 36 ayega. Aur (5-x)² ko expand karenge to 5² - x² + 2×5×x = 25 - x² + 10x hoga. I hope you will understand it.

Wrong wrong 7:00 to 8:06, sir it is not given that AB is perpendicular to CD . So, how you say that it's bisect the chord.

••Sir iss question ka answer toh sirf theory hai . ••Aapka figure bhi wrong hai. ••Jab bigger circle ka radius hi 5 cm hai toh jo aap figure banaye hai unke centre ka distance 4cm kaise ho sakta hai?? •• Iska answer rahega ki JO COMMON CHORD HOGA DONO CIRCLE ME WO SMALLER CIRCLE KI DIAMETER HOGI KYOKI COMMON CHORD SMALLER CIRCLE KE CENTRE SE PASS OUT KAREGA ISKE CORRECT FIGURE ME 🎉 SO DIAMETER OF SMALLER CIRCLE IS LENGTH OF COMMON CHORD WHICH IS 3×2= 6CM
