WebStep 1: Concept and formula to be used. According to the Herons formula, Radii of excircles of a triangle can be given by r 1 = ∆ s - a r 2 = ∆ s - b r 3 = ∆ s - c Where, ∆ is the area of the triangle given by ∆ = s s - a s - b s - c. r 1, r 2, r 3 are the radii of excircles. a, b, c are the length of the sides of the triangle. WebA 5 B 20 Q.16 In any triangle if tan = and tan = then find the value of tan C. [5] 2 6 2 37 Q.17 The radii r1, r2, r3 of escribed circles of a triangle ABC are in harmonic progression. If its area is 24 sq. cm and its perimeter is 24 cm, find the lengths of its sides.
WebThe correct option is A True Let a,b,c be the length of the sides of the triangle, s be the semi perimeter and Δ be the area. r1 = Δ (s−a) = 24 (12−a) r2 = Δ (s−b) = Δ (12−b) r3 = Δ s−c = 24 (12−c) Since r1,r2,r3 are in H.P. ⇒ 1 r1, 1 r2, 1 r3 are in A.P. ⇒ 2 r1 = 1 r1+ 1 r3 or 2× 12−b 24 = 12−a 24 + 12−c 24 Or a+c= 2b .....
