PLANE SURVEYING SU1200 ASSIGNMENT # 2 se appropriate significant figures in your answers! A surveyor paces a 60 m length four times with the following results: 74, 75, 76, 75.5 paces. How many paces, rounded to the nearest full pace, will be necessary for this surveyor to pace a distance of 200 m? A surveyor has determined that the side AC (hypotenuse) of a right triangle (right angle at corner B) has a length of 234.330-m and that the angle at corner A is 38°17'. Determine the lengths of the other two sides of the triangle. The three sides of a right triangle are 60, 80, and 100-m. Determine the magnitude of the interior angles to the nearest degree. The angles at the corners of a triangular field are 32°, 58°, and 90°, and the hypotenus
