If I have the correct numbers,This is one way of doing last Q

Area = ( absinC)/2Sin-1 C

= 18x2/(7x8)= 40.00520088 degrees (DO NOT ROUND)

a^2 = b^2 + c^2 - 2 x b x c= 27.20955764 cm (DO NOT ROUND)

Cos A^-1= (b^2 + c^2 - a^2) / 2 x b x c

= 80.37550115

= 80.4 degrees
Thank you this is really helpful. I think i see where i went wrong, I thought i was working out just the first angle and thought i was done lol
2. Can someone put the marks for each que
3. What was question 16?

7. which question number was the perimeter of the two arcs? And what did people get for it

How could it be "3.8" you baffled horse
3.8 here as well because the number rounded closer to it when I checked 3.75
9. q15 HE IS CORRECT depreciates by 50%
10. I got 3.8 from using 3.75 and it was too small, but when I checked the distances between the two values 3.7 was closer, I left it as 3.8 because they usually award the mark for using 3.75 rather than working out the differences between

The marks should have indicated there was more work to do. Never mind, hopefully everything else went well and Good Luck !!
18. For the last question one angle, two sides and the area are given. Can't you just workout the third side using the area and base then use cosine rule since you have three sides???
