IXL - Checkpoint: Right triangle trigonometry (Geometry practice)

While visiting Seoul, South Korea, Savannah takes a cruise on the Han River. Her favorite part of the cruise is when she first sees the N Seoul Tower, whose top is about 480 meters above sea level, in the distance. The angle of elevation of her line of sight to the top of the tower is

not to scale

If Savannah is about 3 meters above sea level, how far is she from the top of the tower?
