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 maths we can measure angles using bearings. the angle is always measured from north to the given line so you have to start by drawing a vertical line up from the point you're asked to do the calculation on. then you measure the angle from the north line you've drawn to the line you have. you should give your answer as 3 numbers, followed by the ...
