"See, the plants kind of go in a semicircle, but one side of the arc's longer than the other. So whoever planted these must have run out of time or ideas...but it tells us where they started. Here, with the red spider lilies."

Semicircle through E, because ∠AEB = ⦜
Intersection point F is also on the semicircle, therefore ∠AFB = ∠AFC = 90°
△AFC ≅ △BEC, therefore △ABC is isosceles.
Then CG bisects AB and ∠ACB
∠BCG = 40°, therefore ∠ABC = 50° and x = 50°-10° = 40°
