1. A pre-engineering baseline was run down a very steep hill as presented below. Rather than measuring horizontally downhill with the steel tape, the surveyor measured the vertical angle with a theodolite and the slope distance with an EDM. The vertical angle was \( -9^{\circ} 26^{\prime} \) and rod reading was \( 4.88 \mathrm{ft} \) above the ground. The slope distance from the theodolite to the rod was \( 148.61 \mathrm{ft} \). The theodolite's optical center was \( 4.669 \) above the upper baseline station at \( 110+71.25 \). (1) If the elevation of the upper station is \( 324.28 \), what is the elevation of the lower station? Answer: ( ) (2) What is the stationing of the lower station? 2. A five-sided, closed traverse has the followine inectior angles: \[ \begin{array}{l} A=70^{\circ} 10^{\circ} 30^{\circ} \\ B=142^{\circ} 41^{\prime} 60^{\circ} \\ C=83^{\circ} 51^{\circ} 30^{\circ} \\ D=117^{\circ} 25^{\prime} 30^{\circ} \\ E=125^{\circ} 49^{\circ} 60^{\circ} \end{array} \] Deternine the angular crrer and baiance the angles by applying equal corrections to each angle. 3. Express the following directions by the other mean and determine the beokirevetie) directions for the values. Total three values need to be answered,
