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.
A unit for measuring angles. 180Â° = Ï radians, and 360Â° = 2Ï radians. The number of radians in an angle equals the number of radii it takes to measure a circular arc described by that angle. Note: 360Â° equals 2Ï radians because a complete circular arc has length equal to 2Ï times the radius. Formula: Î¸ = s/r. Î¸ = measure of the central angle in radians.
