A plane is headed eastward at a speed of 156 m/s. A 20 m/s wind is blowing southward at the same time as the plane is flying. The velocity of the plane relative to the ground is:

157 m/s at an angle of 7.31 degrees south of east
157 m/s at an angle of 7.31 degrees east of south
155 m/s at an angle of 7.36 degrees south of east
155 m/s at an angle of 7.36 degrees east of south
