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.
In elementary school, we learn that angles are measured in degrees (Â°). 1 full circle = 360Â°. Historical note: The number 360 comes down to us from antiquity. 360 was useful to ancient astronomers because it is approximately the number of days in the year.
