The arms of a Wheatstone bridge ABCD have the following resistances: AB: R, = 1,000 + 1.0% BC: R; = 100 ± 0.5% CD: unknown resistance Ry DA: R3 = 432.5 + 0.2% Determine the value of the unknown...

Hi could i please have the workings out and answer for the question attached.

If possible could you write down any formulas used.

Thank you! :)
