Applying the parallelogram rule ,
R^2 = 4500^2 + 4000^2 - 2(4500)(4000)cos135°
|R| = ......
Use the Sine law to find one other angle of the triangle, then
conclude with whatever you mean by "the angle from the east".
Two tractors, attached to a stump by chains, are being used to pull out the stump. One is pulling with a force of 4000N due east. The other is pulling with a force of 4500N northeast. Let point P represent the stump. Using a scale of 1cm to represent 1000N, find the resulting force and the angle from the east.
