Need help filling this out and finding the magnitude and direction.

A car is parked on a steep incline overlooking the ocean, where the incline makes an angle of 30 degrees below the horizontal. The negligent driver leaves the car in neutral, and the parking brakes are defective. The car rolls down the incline, reaching the edge of a vertical cliff with a speed of 20.0 m/s. If the cliff is 30.0 meters above the ocean, find the magnitude and direction of the velocity of the car as it lands in the ocean. x0 = YO = \"[71\" X = y ~+\\' \\\\\\ \\_'\\:\\\\ _ V : 3i: \\\\\\\\ VOX 0y \\E \\a _ : \\\\ Vx _ V}, \\ a = a = \\ X y \\ ' \\ ,l U. \\_-"\\"\\_.,- t = t
