a. The angle of slope

b. Slope is 1 in 4.5

c. Difference in elevation of A and B = 35.07m

Explanation

a. Horizontal distance =

Alternative Method

  • Correction for the slope distance, =
  • Horizontal distance, D =

b. Slope is given as 1 in 4.5, i.e..

Horizontal distance, D =

Alternative Method

  • Correction for the slope distance, =
  • Horizontal distance, D =
