Would it not be 5.33 kilometers not 5.33 miles?? Sorry not being a smart arse :), just thought you were dealing in K's not miles. Love the vids champ, I am learning more now than I ever did in class and I am 27!!!

It will not be so hairy if it is done this way:
Find x = 5(cos15) = 4.8
FInd y = 5 (sin 15) = 1.3
FInd Z = 4.8 -10 = 5.2
Find M using pythagorean theorem = 5.3
I like your videos a lot though and you are very helpful.
Thanks a lot.

I love how when you get farther into the videos, the views start to drop like people stop watching them lol.

Thank you so much for simplifying this problem. I know I am not in your class, but I appreciate your videos. I am a trig student in South Carolina and I am looking forward to studying more in the future. Thank you.

Hey I just wanted to know if what I know is correct... could you have just used the cosine rule a^2 = b^2+c^2-2*b*c*cos(x). BTW I though that was pretty funny when you said at the end "Have fun!"

Yeah, that would have been faster. I tend to do all my trigonometry using the basic functions when I can (avoids having to memorize things), but you are correct. Maybe I'll do the same problem again that way. thanks.
