T. rex's serrated, cone-shaped teeth were most likely used to pierce and grip flesh. Its two-fingered forearms could probably seize prey, but they were too short to reach its mouth. Scientists believe this powerful predator could eat up to 500 pounds (230 kilograms) of meat in one bite.
Angles and distances are measured from the total station to points under survey, and the coordinates (X, Y, and Z or easting, northing and elevation) of surveyed points relative to the total station position are calculated using trigonometry and triangulation.
The measure of the one angle in the parallelogram is the same measure as the angle opposite it, so: 2(85)+2x=360 170+2x=360 2x=190 x=95 angles are 85, 95 and 95 degrees. A compass alone will not give you the desired result, as it only gives you the distance between the center of the circle and the actual circle, called the radius.
