Answer:

305.54degrees

Explanation:

WE are to find the principal value of tan^-1(-1.4). Principal value means the highest value

theta = tan ^-1(-1.4)

theta = -54.46

Since theta is negative in the fourth quadrant;

theta = 360 - 54.46

theta = 305.54degrees

Hence the principal value is 305.54degrees
