GF in in tension, not compression. -24cos30 + 13.85cos60 + GF = 0
-20.785 + 6.925 + GF = 0
-13.85 + GF = 0
GF = 13.85 Tension

How did you determine triangle 📐 BXG is a right triangle? When you split angle B down the center to create triangle 📐 BXG, angle B becomes 45deg, making the triangle a non right triangle

Ive been scratching my head why I'm wrong Fgf I got was in tension and in your notes it says Compression. I got the same value as well and I double checked and I'm pretty sure its right idk.
I used the right side of the diaram.

[@chrismarklowitz1001]

I checked your diagram and the forces in the x dont sum to 0.
