The diagram shows three vectors. Three vectors drawn on the x y plane. The first vector is 8 blocks long drawn in the positive x direction along the x axis and labeled P Subscript x Baseline. The second is drawn tail to tip method, is 6 blocks high, drawn north and labeled P Subscript y Baseline. The last is drawn from the tail of the first to the head of the second and labeled P. The angle between P and P Subscript x Baseline is labeled theta. Which best describes a relationship among the vectors? Vectors P and Py are components of vector Px. Vectors Px and Py are components of vector P.
