26.

The distsnce and the Azimuth remain same. The incline upon the up and down process

delta 3 to delta 0:-

Distance = 13.6\'

Azimuth = 76 degrees

incline = -2 degrees

Similarly , for delta 5 to delta 0

Distance = 24.6\'

Azimuth = 157 degrees

incline = -23 degrees

27.

horizontal distance between 0 and 3 = 13.6 sin(76) = 13.1960 = 13

horizontal distance between 0 and 5 = 24.6 cos (157-90) = 24.6 cos (67) = 9.6119

28.

3 to 5 measured distance = 13.6+14.2+24.6 = 52.4 feet

incline = -2+2+23 = 23 degrees
