Difference in Elevation between Ground Points in short lines under Trigonometric levelling Solution

Follow our step by step solution on how to calculate Difference in Elevation between Ground Points in short lines under Trigonometric levelling?

FIRST Step Consider the formula

Δh = D p \cdot \sin (M) + h i - h t

Next Step Substitute values of Variables

∴

Δh = 80m \cdot \sin (37°) + 22m - 19.5m

Next Step Convert Units

∴

Δh = 80m \cdot \sin (0.6458rad) + 22m - 19.5m

Next Step Prepare to Evaluate

∴

Δh = 80 \cdot \sin (0.6458) + 22 - 19.5

Next Step Evaluate

∴

Δh = 50.6452018521561m

LAST Step Rounding Answer

∴

Δh = 50.6452m
