OpenStudy (gentorr):
sure
OpenStudy (anonymous):
Its 90 degrees.
OpenStudy (mathmate):
Hint:
PQ makes 60\(^\circ\) with the horizontal, while RS is parallel to the horizontal.
OpenStudy (gentorr):
okay i got 90 because it said that the center of O to pqrf makes 90 degrees |dw:1433889605766:dw|
OpenStudy (anonymous):
oh,Thanks can you help me with a couple more please?

Wait it would be 300 degrees
OpenStudy (gentorr):
how??
OpenStudy (anonymous):
@mathmate Thats what my teacher told me, but i didn't get it...
OpenStudy (anonymous):
Because It would only take 60 degrees to make PQ Line up to RF or 300 degrees to make it happen

unless you go from f to n clock wise
OpenStudy (mathmate):
We are mapping PQ to RF, so P->R, and Q->F
so far so good?
Think of mapping OP-> OR
What is the angle needed (CCW)
OpenStudy (anonymous):
umm you've lost me... is it 60
OpenStudy (mathmate):
In the Cartesian plane, all angles are counter-clockwise.
