Let's do this question angle PSR is equal to 50 degrees.
All right, B is the angle by sector of Oreste angle P, Q as is seventy five degrees, find angle PSU.
All right.
Was the video.
Give it a try and then let's do it together.
All right.
We are back.
Let's do it together.
Let's join Q and s alright so we can see that BSR angle P.
S R is equal to Àngel p e right.
Because it's given that piece is the angle dissector.
So let me write that over here.
PSR is equal to Angle PSG and we market over here.
This AngloGold is also fifty degrees.
All right.
Now Angle DSB.
Right, this angle is formed by BIS which is the second and a tangent.
Right.
So as per second tangent theorem this will be equal to angle B.
R.
S right angle.
DSB is equal to angle B r.
S, which is equal to fifty degrees aspecific second tangent theorem to this market over here.
This angle is also fifty degrees.
All right.
Now over here we have two angles.
Now we have a triangle over here, hence angle our as will be 180 minus fifty minus fifty.
That's equal to eighty degrees.
Right.
So that's angle AAPS.
Now you can see that angle P.
S Q will be 180 minus eight minus seventy five.
Right.
Because it's given that angle because that's P q as this angle over here is given a seventy five.
Right.
We have seventy five at and this is the angle that you need to find.
So that would be 180 minus eight minus seventy five which is equal to twenty five degrees.
