WebSep 28, 2024 · Clue 1: R1 + R2 + R3 = 24 Clue 2: R1 + R2 =16 Since, R1 + R2 + R3 = 24 (from clue 1) R1 + R2 + R3 = 24 16 + R3 = 24 Subtract both the sides by 16, R3= 8 Clue 3: We need to find the blank R1 + __ + S2 = 20 and S2 = 4 Since, R1 + R2 = 16 (from clue 2) So, R1 + R2 + S2 = 20 16 + S2 = 20 Subtract 16 from both sides. 16 + S2 - 16 = 20 -16 S2 = 4 WebSolution The correct option is C ∑ tan A 2 Explanation for the correct option: Step 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.
