Answer:
73.5 km
Step-by-step explanation:
The magnitude can be found from the law of cosines. The angle between the two vectors is 140°, so the magnitude is ...
c^2 = a^2 + b^2 -2ab·cos(C)
c^2 = 32^2 +46^2 -2·32·46·cos(140°) ≈ 5395.2348
c = √5395.2348 ≈ 73.452
The magnitude of the resultant vector is about 73.5 km.
Answer:
sqrt 2
Step-by-step explanation:
Answer:
n>2 (see below)
Step-by-step explanation:
Triangle side rule says n+2 + 5 must be greater than 9
n+2 +5 > 9
n > 2
(but it must be less than 12 o/w 5 + 9 will not be greater than n+2)
