#### Problem (3)

A survey in northern Wisconsin includes NSRS point QN0534 *Brent*. For direction orientation, NSRS point QN0533 *Swayne Tower L* is sighted from *Brent*. An angle of 212°55'14" is turned to the right to traverse point *Dog*. The measured horizontal distance from *Brent *to *Dog* is 1725.63 ft. Dog's scaled elevation is 1385 ft. The survey will be adjusted in Wisconsin's North SPC Zone in survey feet. Constants for the zone include N_{o} = 365,048.99 ft = 111,267.15 m, r_{o} = 20,927,206.92 ft = 6,378,625.43 m.

(a) What is the geodetic azimuth from *Brent* to *Swayne Tower L*?

(b) What is the SPC grid azimuth from *Brent* to *Swayne Tower L*?

(c) Is there a significant arc-to-chord correction for the measured angle?

(d) What is the grid distance from *Brent* to *Dog*?
