um i jst noe the correct method which was 2 use the tangent ..ya,, but i screwed up that question thinking that 69 degree was the 2wice the u noe the angle n got 34,5 but i bet its wrong since its the wrong method,anyways, rly hope 4H wil b better, DOES ANY ONE RMB THE QUESTIONS PROPERLY?

NO. 18 :::: you have an exterior angle in the middle triangle to the right triangle = 2x as it is equal to the angles in the right triangle..................since the middle triangle is isosceles ...the angle next to it = 2x .........we have a larger triangle combining both the middle and the right........its angles is ( 2x.....111.....x).......69 is exterior to this triangle ...so 69 = 2x+x .....x=69/3 .= 23 ....:):)

the answer is 23 degrees....dat questio was sooo easy...da additiom of two exterior angles is equal to one exterior angle which means da outter angle becomes 2x hence u cn figure out the angles in the next triangle and den angles on a straight line adds upto 180 degrees....using algebra u cn wrk it out....da paper was pretty easy dan expected it to be....

Hello guys. First of all i would like to thank you all for discussing this exam, which i think was quite difficult. I want to ask something. Could someone make a list of all the posible topics that are likely to come up on paper 4H? This will really help everybody to focus on these topics. Thanks to all.

highly doubt 90%. it was no where near that easy. I'd guess a low 80. good luck with you too
