Hi there, here we have to solve the given problem.
00:04
Let's start with drawing the coordinates.
00:09
We have north, south is opposite, east is to the right, and west is to the left.
00:19
So first, we start at the origin, and we walk 53 meters to the north.
00:33
So we walk 53 meters to the north.
00:36
Then we turn 60 degree to our right.
00:39
So we turn 60 degrees to our right.
00:45
So we turn.
00:46
Turn by angle alpha of 60 degree to our right.
00:50
And we walk another 45 meters, which brings us to the point three.
00:59
And we have to determine our overall displacement.
01:12
So it means that we have a triangle, a, b, c, yeah, triangle a, b, c, where ab equals to 53 meters, b .c.
01:43
Equals to 45 meters and angle cba equals to 180 degree minus alpha, which is 120 degree.
02:05
Because this angle alpha is 60, 180 minus 60 is 120.
02:11
So, first of all, to find, here we have to find the displacement factor with replay with respect to the east.
02:23
So it means that we have to find this angle better.
02:28
Probably not the best choice of color.
02:31
Let me choose another one.
02:35
So this is angle better.
02:37
To find angle better, there are several ways to find angle better...
