join objects' cordinates wid its image's cordinates and find perpendicular bisector of the lines joined
where thes lines intersect it will be center of rotation

http://clickpapers.net/past papers/math-/4024_s10_qp_12.pdf q.9 part c ??? anyone pls help ?? need to understand it

Dost is sawal mein phele to tumhe ye pata hona chahiye k agr tum kissi ka under root nikal te ho to us ke pairs honay chahiye under root mein like
if (squareROot4) then we can write (squareRoot 2 x 2) yaha 2 ka ek pair hai to wo root k bahar ajeaga thus Squareroot of 4 will be
just like (SquareRoot8) is mein hum likh saktay hai (SquareRoot 2 x 2 x 2) to ye hojae ga (2SquareRoot2) q k yaha ek pair tha to ek 2 bahar agaya aur unpaired 2 ander he reh gaya now returnig to question

168 = 2^3 x 3 x 7
is ko agr perfect square banana hai to har kisi kay complete pair honay chahiyay, thus 2 ka pair kar nay liya 2 se multiply karegay 3 ka pair complete karnay k liye 3 se multiply karegay and so for 7
thus n = 2 x 7 x 3 = 42

omg such a difficult question ... seriously???

 

[Sarah22]

7 b (iii) u calculated area of triangle AOB
like 0.5 x 9 x 9 x sin 140 = 26.03 cm2
height of triangle will be 0.5AB/tan 70
then area of triangle will be 0.5 x b x h
0.5 x 0.5AB/tan70 x AB = 26.03
AB = 16.9cm (tell me if its correct)

The others are correct, but this answer is not correct..

tariqa yahe hai, tum phir se sukoon se try karna mein ne direct yaha solve kia to isliye mistake kar gaya hoon
