Question1

A hiker makes four straight-line walks A 20 km at 274^o B 12km at 48^o C 33 km at 150^o D 30km at 20^o in random directions and lengths starting at position (41 km, 41 km)
How far from the starting point is the hiker after these four legs of the hike? All angles are measured in a counter-clockwise direction from the positive x-axis. 

Question2

Suppose your hair grows at the rate of 1/32inche per day. Find the rate at which it grows in nanometers per second. Because the distance between atom in moleclule is on the order of 0.1nm, your answer propose how rapidly atom are assembled in this protein synthesis
