7. Albert is standing at point A. He takes a sighting to the top of a cliff, (point C). The angle of elevation is 30°
degrees. Becky is standing at point B and takes a
sighting to the top of the same cliff, (point C). The
angle of elevation is 45° degrees. If the cliff is 100 feet
high, find the exact distance between Albert and Becky.

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.

Ithink it is space that makes up 70 percent
