The slope distance between two points was measured with an EDM and found to be 1223.88 ft. If the zenith angle (the angle from the vertical to the line) is 95°25'14", compute the horizontal distance. (Ans.: 1218.41 ft) 385.11 ft) 2138.77 ft) 10

Respuesta :

Answer:

Horizontal distance = 1218.41 ft

Step-by-step explanation:

Given data:

Slope distance = 1223.88 ft

Zenith angle is  = 95°25'14"

converting zenith angle into degree

Zenith angle is [tex]= 95 +\frac{25}{60} + \frac{14}{3600} =[/tex] 94.421°

Horizontal distance[tex]= S\times sin(Z)[/tex]

putting all value to get horizontal distance value

Horizontal distance [tex]= 1223.88\times sin(95.421)[/tex]

Horizontal distance = 1218.41 ft
