Answer:

x = 23.125°

Step-by-step explanation:

∠ACF = ∠GCB (vertically opposite angles)

3x + 5x - 5 = 180° (angles on a straight line are supplementary)

8x = 185°

x = 23.125°

This is a question on angles. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)
