Help With PreCalculus Problem From a certain distance, the angle of elevation to the top of a building is alpha degrees. At a point 75 metres closer to the building, the angle of elevation to the top of the building is beta degrees. a. Find an equation in alpha and beta for the height of the building. b. Find the building's height if alpha = 20 and beta = 35. The equation they got was h = (75 sin alpha) / sin (beta - alpha). I don't get how they got the equation. Also, when I plug in alpha and beta into the equation, I don't get 56.85 like the answer key says. Can any of you guys help me? Thanks in advance!

I Can't Stop Thinking About Her My great grandma, that is. She is/ was on life support and they will/ have pulled the plug. I just can't get this out of my head. She fell a few weeks ago and got stitches for her head. What really frustrates me is that this could have been prevented. You've lived a long 93 years. R.I.P. I wish I could have visited you more often, since you live so far away. I didn't even get to say goodbye. :( I've been through this same situation almost six years ago with my grandpa, whom I was much closer with. I'm not usually one to dwell on the past, but this just brings back so many bad memories from that one moment in time. I'm struggling through my homework at the moment, so...I'm turning to you, Basilers. How do you
