Consider three vectors a⃗ ,b⃗ and c⃗ all lying in the xy plane. vector a⃗ has length 6.2 and makes an angle of 131 degrees with the x-axis. vector b⃗ has length 7.3 and makes an angle of 32 degrees with the x-axis. the vector d⃗ =a⃗ +b⃗ +c⃗ has x-component dx = 3.1 and y-component dy = 6.7 .a) find the magnitude of the vector c⃗ .b) find the angle in degrees that vector c⃗ makes measured counterclockwise from the x-axis.
