Sir, 25:20, question 21(b) is obviously wrong. In fact, there is no correct answer in this question, as both answers "Yes" and "No" are equally wrong. Correct answer is "not enough data to say". In your solution (which is also the one suggested in the marking sheet) you only check a _necessary_ condition, which means that X *could* indeed be the centre. But this is not enough to say whether X *is* the center. In fact, if we draw a circumscribed circle around ΔCXD, then any point Y on CXD arc would give us ∠CYD=156°, which is double the angle ∠CED. Would that make them all centers of the original circle? Of course, no.
So there is a blatant logical error there, which was quite shocking for me to find in a national school qualification paper. The fact that this error goes unnoticed is even more shocking.

In Q29, why is SinC = Sin114? isnt SinB = 114.

Sir The Grade ( out of 80 ) u said in description is it right?
That if i get 10 Marks on the higher paper in 2023 if i get 10 marks i will get grade 3?

sir u said that
*In an Hour he is covering 12 miles*
and u also wrote 30min = 12 miles?
can u please explain

[joumaalbatran]

sir q29 is wrong when i type 0.5x8x10xsine(144) it equal to 23.51141...

[study-plmj]

for question 29 why did you use the cosine and sin rule?
