Hi guys,

I am having trouble with this word problem:

If someone could point me in the right direction it'd be much appreciated! I've just been banging my head against a wall on this one .Two buildings face each other on opposite sides of a city square. The angle of depression from the top of the taller building to the base of the shorter is 38 degrees. The angle of depression from the top of the shorter building to the base of the taller is 23 degrees. If one building is 30 m higher than the other, how wide is the square?

Thanks,
