In a \triangle {\ABC}, the sides {\b}, {\c} are fixed. In measuring angle A , if there is an error of \delta {\A}, then the percentage error in measuring the length of the side a is [TG EAPCET 10 May 2024 Shift 2]

Correct Answer is : ∆δA2R2sin2A×100

{2 ∆ \delta {\A}}/{ {\R} \sin {\A}} \times 100

2 \times {\delta {\A}}/{ {\A}} \times 100

{∆ \delta {\A}}/{2 {\R}^2 \sin ^2 {\A}} \times 100

{∆^2 \delta {\A}}/{ {\R} \sin {\A}} \times 100
