i always have trouble finding the interior angles.. and the bearing questions on my tests are almost never for right angle triangles. if they were, we could easily use SOH CAH TOA, like you should've done with this example. please do a non-right angle triangle example! :(
@Inferno0619 He could have chosen either angle, but choosing the 15 would've ALSO led to tan (rather than sin like you asked) because the known sides are opposite and adjacent. Using that knowledge leads you to ... tan (15) = x / 23, and I assume you can figure out the rest :)
Those taking the merchant marine certification test for fishing guide are tested for navigation skills. Could you provide the skills to past those few mathimatical navigation questions. The difficulty of navigation part of the exam is far and above 905 of the MMC manual questions. For these navigation question candidates often have to quit self study and go to significant, sometimes prohibitive expense to enroll in a brick and motor school to complete an exam that otherwise would have been attainable online.
hi,i have a problem stating that..Airport B is 200 mile due east of airport A.T reach airport C,a plane flies from A on a course of 346.35 degree or from B on a course of 302.2 degree. Find the distance from A to C and from B to C. thanks!
i get how he figured out the problem, just don't know why he used the 75 degree angle to solve it instead of the 15 degree angle, he could have used sine function to do it too couldn't he?
I don't understand why the time would be the same because one boat could go for 15 mins (for e.g) and get to one spot while the other boat traveled 10 minutes to get to the same spot so I don't see how u can suppose the times are the same without knowing all the triangle lengths first
I think no, because you know, it's a right triangle and sine and cosine rules are for acute and obtuse angles. I'm not sure if they ACTUALLY work with right triangles too somehow. But still right angled triangles trignometric formulas are the best option here.(or maybe the only)
They really said "A smuggling craft from the cartel carrying 20 tons of cocaine is simultaneously traveling at a course of 195 degrees from Venezuela" roflmao
I understand EVERYTHING!.. until 4:55 i dont get the bit where he got the 23 knots(wat is that?) anyways.. and how did he knw that that length was 23t?? isnt 23 the speed! not the distance... ??? and why is 't' there?? wat does t stand for?? and lastly 'x t'?? wat is thatttttttttttttttt?????????????????????????? plz help. quick my exam is next week!!
Hope you passed your exam. Knots are a unit of speed in boating world, it's like km/h. The distance is the speed x time, and t is time. xt: x is the speed of the second boat, t is the time, which is the same since they both started at the same time. You probably know this by now, but just to help others who might come across this video years later.
