PAGE 194 QUESTION 3 PART A

ANY HELP WOULD BE APPRECIATED

 

[CaptainDanger]

I would extend the line PQ... Then draw a line parallel to the extended line from point R.. And measure the angle...

 

[yousef0074]

hey, i appreciate your help but didn't the question say 'calculate'???

i also tried solving it by extending two lines like you did, so making an iscoscles triangle

 

[CaptainDanger]

Yeah its calculate... But I don't know how to do that... May be someone else can help us?????????????
