Geometry P106 Question 10 wording

[yeji_dwaji]

If the question is asking the angle 40 degrees, why is it written ACB, wouldn't it be ABC since the angle is in between A and B? Also when it's asking the arc AXB, is it asking about the arc AX? Are angles and arcs always written this order?
Thank you.

Hey Yeji,

Yeah, looks like we have some typos there! Thanks for catching it! (Looks like the explanation says the same thing, too! Strange!). Clearly we meant angle ABC is 40, and we're solving for arc AXC. Apologies!
