From the top of a 1900 m mountain, the angle of depression to a cathedral that is due east of the mountain is 38 degrees. The angle of depression to a bridge due north of the mountain is 42 degrees.

Find the straight-line distance from the cathedral to the bridge.

This is a question that needs visualizing as it has no diagram, but i know I have to draw a North/East/South/West grid.
