Projectile motion radar antenna

[physics0926]

Homework Statement

A radar antenna is tracking a satellite orbiting the earth. At a certain time, the radar screen shows the satellite to be 162 km away. The radar antenna is pointing upward at an angle of 62.3 degrees from the ground. Find the x and y component(in km) of the position of the satellite.

Homework Equations

Vx=dx/t ..... a=Vy-V0y/t ... Vy+V0y/2 = dy/t

The Attempt at a Solution

its a simple question but I am thinking too hard

V0y=Vo (cos) angle
Vx= Vo(cos) angle
dx?

Its just working out the lengths of two sides of a right angled triangle given the hypotenuse and angle. Draw a diagram of the situation and it will probably be a bit clearer.
