It is intended to connect two straight lines, which intersect at station $6716\mathrm{.}68$ at an angle $25\backslash$deg with a simple circular curve. Find the minimum degree of curvature of the curve $($rounded to the nearest $30)$ so that the length of the tangent is less than $85$ metres, then calculate the angles of deviation for all points of the curve that are far from the beginning of the road $(0+00$ Sta$)$ in multiples of twenty metres.
