The vector v is the resultant vector of the velocity vectors v1 and v2.Vector v1 has a magnitude of 3m / s and a direction of 150 ° (starting from the axis Ox, with rotation in the opposite direction) The vector v2 has a magnitude of 10m / s and a direction x. If knowing that the direction of v is 90 °, calculate: a) the value of the angle x and b) the magnitude of v
