The rectangle shown in a Figure has sides parallel to the x and y axes. The position vectors of two
corners are A = 10.0 m at 50.0° and B = 12.0 m at 30.0°. (a) Find the perimeter of the rectangle. (b) Find the magnitude
and direction of the vector from the origin to the upper right corner of the rectangle.
Find the x- and y-projection of A and B:
The y-coordinate of the top right corner is Ay so, having x-coordinate equal to Bx, the magnitude of R:
