Trigonometry Angle of Elevation?

I could use a little help in trying to figure these two problems out:

A boat travels for 8km in a straight line from the dock. It is then sighted from a lighthouse that is 6.5km from the dock. The angle determined by the dock, the lighthouse (vertex), and the boat is 25 degrees. How far is the boat from the lighthouse?

You are skiing down a mountain with a vertical height of 1500 feet. The distance from the top of the mountain to the base is 3000 feet. What is the angle of elevation from the base to the top of the mountain?

Please show your steps so I can learn something!
