Angles, Degrees, and Arcs
Hey there, I've got a few questions.
I have no idea how to figure out these kind of word problems. I'm taking an online class and I've got no source of help but here. So, is there some sort of formula I must follow with these? Draw a diagram? What does the "bearing" of 42.26 do for me?
A fire is sighted due west of lookout A. The bearing of the fire from lookout B, 8.6 miles due south of A, is N 42°26'W. How far is the fire from B (to the nearest tenth of a mile)?
Oh, and this one is probably easy, just simple algebra and such, but I dont know what to do... sin A = cos 3A
Thanks in advance, Juan.
