Let's do this question in the figure below, Angotti is 50 degrees and Altisource is 140 degrees.
That's this angle angle B or S, that's this angle that's 120 degrees and angle are askew.
That's this angle is what we need to find.
All right.
Was the video.
Give it a try and then let's do it together.
All right.
We're back.
Let's do it together.
We have these three angles, right?
We have been given these three angles and we need to find angle rescue.
All right.
Now you can see that over here, PTSA is forming a quadrilateral.
Therefore, because I have these three angles, I can find this angle by doing 360 minus some of these
triangles.
Right.
So angle is equal to 360, minus 50, plus 140, plus 120.
That is equal to 50 degrees.
All right.
So I have angle B is equal to fifty degrees.
Now you can see that pretty skewed.
That's p t.
S Q This is a cyclic quadrilateral, right.
Because all the word is, as you can see, are on the circle.
So askew is that cyclic quadrilateral.
Now, we know that in a cyclic quadrilateral, the some of the opposite angles is equal to 180 degrees.
So to be O plus DSU will give you 180 degrees.
Therefore, you can see that DSU is equal to 180, minus 50.
That gives you 130 degree, right?
Because, you know, DP, all that's what we found over here is equal to 50 degree angle to skew this
angle over here is equal to 130 degrees.
All right.
Now you can see that angle to askew angle Q.
S are these two former linear, right?
This is a straight line.
Therefore angle DSU plus angle are askew is equal to 180 degrees.
And we know angle to skew is one thirty degrees.
Therefore Angle RFQ will be 180 minus 130.
That's equal to 50 degrees.
And that is the answer to this question.
