Given the following information, compute the elevation for TP$1.$ Compute the elevation of TP$1$ after correcting the BS rod reading and the

FS rod reading for "curvature and refraction" given:

$"$BM A$"$ elevation $=558\mathrm{.}00\text{'}($NAVD

BS $($plus sight$)$ rod reading on $"$BM A$"={10\mathrm{.}00}_{?}$ at a horizontal distance of

$1,650$

FS $($minus sight$)$ rod reading on $"$TP$1"={3\mathrm{.}00}_{?}\text{'}$ at a horizontal distance of $1,{300}_{{?}_{?}}$

Round final answer to $2$nd decimal place $-$ don't enter units

Example answer: $642\mathrm{.}93$

Answer:

$3\mathrm{.}910$ Compute the corrected BS rod reading $($apply curvature and refraction for differential leveling$)$:

BS $($plus sight$)$ rod reading $=0\mathrm{.}93$ feet

HD $($Horizontal distance$)$ from instrument to rod $=902$ feet

Round answer to $2$nd decimal place $-$ don't enter units

Example answer: $4\mathrm{.}25$

Answer:

$9\mathrm{.}03$

Question $5$

Compute the corrected FS rod reading given. $($apply curvature and refraction for differential leveling$)$

FS $($minus sight$)$ rod reading $=3\mathrm{.}88$ feet

HD $($Horizontal distance$)$ from instrument to rod $=1,538$ feet

Round answer to $2$nd decimal place $-$ don't enter units

Example answer: $6\mathrm{.}87$

Answer:

$1\mathrm{.}534$ Trigonometric Leveling

Instrument height $($hi$)$ and rod height $(r)$ are the same.

Instrument is at Point $"$A$".$

Elevation of "Point A$"=750\mathrm{.}75$ feet

Slope distance $($SD$)$ from "Point A$"$ to "Point B$"=1,298\mathrm{.}70$ feet

Zenith angle from "Point $A"$ to "Point $B^{\text{'}\text{'}}=86-38\text{'}-10"$

Compute the elevation of "Point B$"$ after correcting for curvature and refraction $($c$+$r$)$ for

trigonometric leveling.

Can someone help me with the EXACT CALCULATIONS of this problens step by step. I appretiate it$.$ Round final answer to $2$nd decimal place.

$($example answer $=846\mathrm{.}52)-$ don't enter units

BM elevation $=895\mathrm{.}93$ feet

Backsight rod reading $(BS)=6\mathrm{.}38$ feet

Foresight rod reading $(FS)=7\mathrm{.}99$ feet
