The x component of vector is 5.3 units, and its y component is -2.3 units. The angle that vector makes with the +x-axis is closest to

Answer 1

tan (angle) = y/x = -2.3/5.3 In fourth quadrant
so angle = -23.46 degrees
about 23 degrees below +x axis

Answer 2

The x component of vector is 2.3 units, and its y component is 5.3 units. The angle that vector makes with the + x-axis is closest to
