Sin 20 = A x / 145 A x = 49.6 m Cos 35 = B x /105 B x = 86.0 m A x + B x = 135.6 m

A jogger runs 145m in a direction 20.0 degrees east of north (vector A), and then runs 105m in a direction 35.0 degrees south of east (vector B). Using components, determine the magnitude and direction of the resultant vector C for these two displacements.
