With the instrument set at point $12$ and backsighting point $10,$ using the observation information below,

Calculate the coordinates and clevation of point $12.$

Calculate angle right and distance to set out points $1,2,3,$ and $4.$

Calculate the cut or fill of $1,2,3,$ and $4$ using the existing ground elevations of $1001,1002,1003,$ and $1004$

respectively.

Draw a stake for $1,2,3,$ and $4$ showing proper cut and fill markings.
