Explanation / Answer

Let, A = 100m, B = 250 m, C = 150 m, D = 200 m

Ax = 100m

Ay = 0

Bx = 0

By = -250 m

Cx = -150*cos(30) = -129.9 m

Cy = -150*sin(30) = -75 m

Dx = -200*cos(60) = -100 m

Dy = 200*sin(60) = 173.2 m

a) Rx = Ax + Bx + Cx + Dx

= 100 + 0 - 129.9 - 100

= -129.9 m <<<<<<<<<<<<--------------Answer

b) Ry = Ay + By + Cy + Dy

= 0 -250 - 75 + 173.2

= -151.8 m <<<<<<<<<<<<--------------Answer

c) R = sqrt(Rx^2 + Ry^2)

= sqrt(129.9^2 + 151.8^2)

= 200 m <<<<<<<<<<<<--------------Answer

d) theta = 180 + tan^-1(Ry/Rx)

= 180 + tan^-1(151.8/129.9)

= 180 + 49.4

= 229.4 degrees <<<<<<<<<<<<--------------Answer

e) R = Rxi + Ryj

= ( -129.9 i - 151.8 j )m <<<<<<<<<<<<--------------Answer
