Hi everyone in this question they have given the plane take off from the airport this slide down the point a 210 kilometer at the distance and degree is 20 degree angle and then for this point north to this is north to east north of east and in direction where west of the north which is equal to 30 degree angle the distance is 235 kilometer we have to calculate the distance and direction from the the from down b.
00:33
So this point i take b so this point from down b we have to calculate and using graphical method now this is the information which is given in the sum and distance we have to calculate for this d x which is equal to for point b so we take this south of this direction so, 210 and this is 235, 210 fine angle, so cost 20 x -axis like this, cost 20 i vector minus 235, sine 60 i vector.
01:32
This is for i component.
01:34
So my, if you minus means, you get a 6 .18, i cap, for 5.
01:40
For d, y component distance, 210, sine 20 j plus 235 cost.
01:59
Here, we have to minus it.
02:02
So 60 minus 30.
02:04
30 j.
02:11
30 j cap...
