Question

Use a scale drawing to find the x- and y-components of the following
vectors. In each case, the magnitude of the vector and the angle,
measured counterclockwise, that it makes with the +x-axis are given
B) magnitude 15km, angle 225

Answer 1

$$a_x=15\cos 225^{\circ}=-10.6\:\rm km$$

$$a_y=15\sin 225^{\circ}=-10.6\:\rm km$$
