A sample of delta-Fe, see phase diagram below, is produced and taker to VD? Given a lattice parameter (a) of $2.92\stackrel{?}{A}$, what angle of 2 -theta (in degrees) would you expect the first XRD peak to be located at if $\mathrm{Cu}$ (lambda = $1.54\stackrel{?}{A}$ ) was used as the X-ray source? (one decimal place)
