3) From two tracking stations A and B, 350 km apart, a UFO is sighted at C above AB making angle CAB = 32 degrees and angle CBA = 54 degrees. Find the height of the UFO. The answer is 150 km, please explain to me how 4) from a boat on the water, the angle of elevation at the t...

Thanks! That makes total sense; I understand how to get the equivalent expressions now (: And I'll definitely remember the signs
Math
I asked that because that's what it says in my notes, and I don't understand it; But thank you for all the help you've given me
Math
But why is the sin, cos, and tan of the principal angle equal to the sin, cos, and tan of the related acute angle?
Math
Though they aren't homework questions I really am desperate to understand the answers to these questions as I have a quiz tomorrow
Math
How does the related acute angle help to determine the trigonometric ratios of angles greater than 90 degrees? (in terms of the Cartesian plane) And why is the sin, cos, and tan of the principal angle equal to the sin, cos, and tan of the related acute angle?? These aren't...
Math
Thank you! You've been an immense help
Math
Am I missing something? I think it's a little different because there's a 150 degree angle that starts in quadrant one and goes to quadrant two, called the principal angle, and the left over 30 degree angle made by the original 150 degree angle is the related acute ang...
Math
If you can make out example 2 (the image enlarges) it's basically saying that angle 150's ratios are equal to angle 30's ratios...? Basically, that you can find the ratios of the principal angle using the related acute angle?
Math
Okay, so, I uploaded a picture of a portion of my notes which I don't understand; it's what I meant when I asked my question about how the sin, cos, and tan of the principal angle is equal to the sin, cos, and tan of the related acute angle. imageshack.us/f/90/imgoc.pn...
