Q A simple horizontal circular curve has: $R=88m$

$T=36\mathrm{.}8m,C=68m,L=69m,E=7\mathrm{.}3m,M=6\mathrm{.}8m=45{24}^{\text{'}},$ StaP.C $=3983\mathrm{.}2m,$ staP.T $=40\mathrm{.}52\mathrm{.}2m$

StaP.I $=40+20m$ Calculate:

$1-$ Coordinates of station $($P$.$I, P$.$T$)$ if a Zimuth of P$.$T longrightarrow P$.$C $=280$@$7^{\text{'}}$ and cor dinate of P$.$C $=(250,250)$
