WebDec 15, 2024 · A negative value for the adjacent means travelling in the opposite direction, i.e. left of the origin. So it would make perfect sense to have a negative hypotenuse, but this would mean the angle is not where you expect it to be: a hypotenuse of − 2 means going 2 units in the opposite direction to that given by the angle. WebNote: Since 120° lies in the 2nd Quadrant, the final value of tan 120° will be negative. We can use trigonometric identities to represent tan 120° as, cot (90° - 120°) = cot (-30°) -cot (90° + 120°) = -cot 210° -tan (180° - 120°) = -tan 60° ☛ Also Check: tan 0 degrees tan 270 degrees tan 90 degrees tan 25 degrees tan 2000 degrees tan 1290 degrees
