Let's do this question, the angles between south and east and north, east and northwest are all right
over here.
We have two angles.
This is the first angle, which is the angle between south and east.
And this is the next angle, which is between the direction northeast and northwest was the video.
Give it a try and then let's do it together.
All right.
We're back.
I hope you have given it a try.
This is a basic question, but it helps to solidify our understanding of the fundamentals.
Let's press on over here.
We have the four directions north, south, east and west, north and south are opposite to each other.
East and west are opposite to each other.
And you can know that the angles between north and east or eastern, south, south and west and west
and north are all 90 degree angles.
All right.
Now, when we talk about the directions north, east and north west, this is the direction north east,
the direction north east is dividing the angle between north and east in equal halves for this angle
is forty five degree.
And similarly, this angle over here is also forty five degrees.
All right.
Now let's mark our angles.
As for the question, this is angle one and this is angle to the angle between northwest and north east.
That's one of the angles mentioned.
Let's call that angle one and the angle between south and east.
That's the other angle.
Let's call it angle two.
Now, why is this angle over here also?
Ninety degrees.
It's because North West also divides the angle between north and west in equal halves.
But this is also equal to forty five degrees and this is also equal to forty five degrees.
Therefore, the angle between north west and north east is forty five plus forty five, which is also
equal to ninety degree.
And similarly we have seen that the angle between South and east are also ninety degree.
So over here both the angles are equal to ninety degrees.
Now when we are these together, angle one plus angle two is equal to 90 plus 90, which is equal to
180 degrees.
That means these angles are supplementary and the correct option is answer B.
