help please

Where is the referred to figure ? 

here's the diagram

1. Connect $RG$

2. Since $FR=FG$, triangle $FRG$ is isosceles with $F$ as the vertex.

3. Angle $GRF$ subtends arc $GF$, which is 130, therefore angle $GRF$ = 130/2 = $65$

4. Since $FRG$ is isosceles, that means $FRG=RGF$.

5. Angle $GFR$ = $50$ because all triangles have an angle sum of 180, and we know that two angles are 65 degrees. (180 - 65 * 2)

6. Angle $PGF$ subtends arc $FQ$, so angle $PGF$ = 28/2 = $14$

7. Conside triangle $PFG$, we know the measure of two angles $GFR$ and $PGF$ is  $50$ and $14$, respectively. That means the third angle $GPF$ is 180 - 50 - 14 = $116$

8. By supplements angle $RPG=180-116 = 64$
