i think that determinant is only for square matrices

Alright thanks for help

O/N/11 P12 Q9
Anyone plz??

let x be ext angle
then
x + int angle=180
x+px=180
x(1+p)=180
x=180/(1+p)
b)
x=360/no of sides
180/(1+p)=360/n
n=360(1+p)/180
n=2(1+p)

Why arent the papers section opening up

 

[usama321]

And what shud be the length of the arcs?

just make perpendicular bisector from two corresponding vertices, as you do in loci questions

 

[usama321]

and it is a fact that you have to open the campus more than half the distance between the two points

That's what I wanted to know . Thanks

 

[farhan141]

I tried it but I still dont get the exact points. Usama suggest me hardest paper 1. I wanna assess myself.

look, in the factors of 360 we have 3^2 n 5^1 other than 2, to make each of 3 n 5 a cubic no. we must multiply it with 3^1 so it will become 3^3 n with 5^2 so it will become 5^3

Oh Right.. Got It Now Thanks!!

1/1-x +2/1+x +2x/x2 -1 I know it's an easy question but someone please tell me how to simplify these types of questions any one pleeaaazzz???!!

9 b

X= 5+4+2= 11

10 b

Take out Lcm of 180 and Solve the rooot

answer would be 6√5
so compare it with p√q

Can u please post the paper link. It is better to understand the problem

Look, (1-x) (1+x) =x^2 -1^2

So, multiply the first fraction by 1 +x, the second by 1-x and the third by nothing. This will give you x^2 -1 in the denominator. Solve the numerators and simply.

thanku so much!

Someone please tell me how to find out the translation vector because I forgot!!

Q.15 (b) plsss

3^2*12-3*2^10)/(3*2^8)
3^2*2^12/3*2^8 - 3*2^10/3*2^8
3*2^4-2^2
3*16-4
44

CPQ and ABC are similar
(4/6)^2=6/x
x= 4/9*6= 13.5
