I start walking. The 1st leg of my trip I walk da = 105 m at θₐ = 25° south of east. The 2ⁿᵈ leg of my trip I dB = 125 m at θᵦ = 15° north of east. On my final leg I walk dc = 95 m at θ = 61.5° north of west. Choose the coordinate sys so that x is directed towards the east, and y is directed towards the north.
Write an expression for the x-component of the final displacement in terms of the given quantities.
Rx =
