Hi, Drifus and welcome to yet another tutorial video, videography. In this video I'm covering true bearing and magnetic bearing. So I'm going to try first to cover true bearing and do magnetic bearing after calculating or finding the true bearing. So let's get to it. So say you were asked to find the true bearing from trick bay corn 178 over here to trick bay corn 183 over here. The first thing you need to notice the width from N2 and when you start that's where you're going to that's where you're going to put your true node. So let's break this out. So first thing you need to do is join the two, the two trick bay corn with a straight line. And then our question says from 178. So from here that's where we'll put our true north. So your true north needs to be parallel to your longitudinal line over there and you should start right in the middle of the trick bay corn over there like that. The reason for your true north to be parallel to the longitudinal line is for you to be able to precisely and accurately measure the true north as accurate as possible. So what you need to do after doing it because you have your true north and your line joining the true bay corn switches from 178 to 183. It's just to measure the angle between the true north and this line in a clockwise direction. So let's try to do that. So in so doing this T junction over here it needs to be directly in inside the trick bay corn and your line or this line of a protractor over here it needs to be directly parallel or are joined to this line over here. And then you can just measure your true your true bearing. So what I'm getting here this is 90. This is 91, 92, 93 and 94. So what I'm getting is 94 to be accurate. So my true north or true bearing rather from trick bay corn 178 to trick bay corn, trick bay corn 183 is 90, 94 degrees. So it is important to note that you're going to count right at the zero o'clock over here. So it's 10, 20, 30, 40 up until 90 and then you just add whatever that after 90. So I got 90, 94 degrees. So let's reverse the question. What if you were asked to calculate or to find the true bearing from 183 trick bay corn over here to the 8178 trick bay corn. We still do the same thing. So the first thing remember is to draw your true north where you need to start which is your from. So I'm going to draw my true north over here which is from 183 and already these lines are already joined. So from here how I measure my true bearing is still the same way or the same method as I did before. I need to measure from this true true north over here. Proquies up until this adjoining line over here. So let's let's do it. So we all know that if I put my rule over here inside this, this is 180. This is 180. So this will be 180 plus the angle whatever angle I'm going to measure over here. So I know I have 180 plus now I'm going to measure the side and I still do the same thing. I line my triangle to the inside of the trick bay corn and this line I need to be right on my true north over there and I still get 90. This is 0. So up until 90. This is 19. This is 94. So I mean 180 which is that angle plus 90 plus 94 will give me 2 180 plus 94 will give me 274 degrees. So that's my true bearing from this trick bay corn over here to that one over there. So let's try to calculate magnetic bearing from what we have found from the first one which was 94. So the main magnetic declination of this map I'm using is 23 degrees 0, 1 minutes westwards. So in calculating the magnetic bearing the formula is magnetic bearing equals to true bearing plus magnetic declination. So the first true bearing calculated was 94 degrees plus you just take this magnetic declination or the one you have calculated but this one is the mean magnetic declination and you add it to the true bearing to get magnetic bearing. So 294 degrees plus 23 degrees 0, 1 minutes. So let's punch this into the calculator. So this is 194 plus you only add degrees to degrees. So 194 plus 23 equals to 170 degrees and say 170 degrees 0, 1 minute and note that I'm not putting in direction because magnetic bearing does not include the direction. So in this case this is your, this is your answer. I hope you guys understood or learned something from this video.
