Two vectors 10N and 20N are inclined at angle 60°to each other. Find the resultant force and direction of d vector

Answer 1

Draw the diagram, and use the law of cosines to find the diagonal.
Then use the law of sines to find teh angle needed.

Or, treat the vectors as complex numbers and just add them.
Convert the result to polar form.

Answer 2

F1 = 10N[0o].
F2 = 20N[60o].

Fr = 10[0o] + 20[60o].
Fr = (10*cos0+20cos60) + (10*sin0+20*sin60)I,
Fr = 20 + 17.3i = 26.5N[40.9o].

Answer 3

Pls how do u get 26.5

Answer 4

20 N to the East, 20N to the west and 10N to the North
