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.
Degree measure. To measure an angle in degrees, we imagine the circumference of a circle divided into 360 equal parts, and we call each of those equal parts a degree.. Its symbol is a small 0: 1Â° -- 1 degree.. The full circle, then, will be 360Â°.
