WebEasy Solution Verified by Toppr Correct option is B) Given: ar(PQR)ar(ABC)= 4925 In two similar triangles, the ratio of their areas will be equal to the square of the ratio of their sides. Hence in ABC and PQR, ⇒(QRBC)2= ar PQRar ABC ⇒(QRBC)2= 4925 ⇒ QRBC= 75 ⇒ 9.8BC= 75 ⇒BC= 75×9.8=7 Solve any question of Triangles with:- Patterns of problems > Web(Take π =3.14) Solution Given, a chord AB of length 10 cm and radius = OA = OB = 5√2 cm. Construction: Draw OC perpendicular to AB. Now, AC = BC = 10/2 = 5 cm [The perpendicular drawn from the centre of a circle to a chord always bisect the chord.] In triangle OAC, sin x = Perpendicular/hypotenuse = AC/ OA = 5/5√2 Similarly, ∠BOC = 45° fitfoodfresh.com
