Angles Q and R congruent hai. So SAA theorem se ho jaega na bhai?
Q and P equal thdi he...yeh kaha diya hua he..shayad mera aaj dimag nhi chal rha he
@gs4890 said:
boss b option dubara paddo
incorrect shit yaar....option D

Bhai, Q and R angles ko mark kiya hua hai, isliye equal assume kar liya..

bhai i'm gettin....PQS ~RPS........nd........PSQ~RPQ........no congruency is possible
but dere is no option lyk dis........where is d problem??????

DS question:

mere hisab se hone nhi chahye....but option a b c galat he..so by D is correct ..assume krne pe they are conguent otherwise they are not

hmm..but if they are not equal, vahan kuch bhi mark nahi karna chaiye tha. If they have marked those two, equal lena chaiye IMO

What is the length of the tangent drawn from the point (2, ˆ'1) to the circle3 x^2 + 3 y^2 + 4x + 2y + 6=0 ?

try again
Bhai congrunt to koi aa hi nai rha
sab sides calculate kr li
so 1 and 3 are correct so b hoga.
Draw out figure and calculate all sides.
take 3,4,5 triangle

DS question:
can be answered by using a alone ?

5/3?
@Messy_19 said:
DS question:
combining both ....v vill get.......A is faster dan B???
@Messy_19 said:
DS question:
1 alone?
@Messy_19 said:
DS question:
1 alone
@Messy_19 said:
DS question:
Only I sufficient.
Only II insufficient
@gs4890 said:

i think while using a alone.......for lenght of platform greater dan tht of B.....b is faster
for oder case A is faster ........so not a clear answer.......
but by combining both v get A is faster.........BTW ur take(explanation)........

bhai iska OA bata?

radius of circle is imaginary.......so no tangent possible.........

3 x^2 + 3 y^2 + 4x + 2y + 6=0 ?
x^2 + y^2 + 4x/3 + 2y/3 + 2=0 ?

center at (-2/3,-1/3) , radius = root(4/9+1/9 - 2) ? kuch gadbad lag rhi hai..

Yep, radius imaginary aa raha hai!


and OA for the DS question is USING BOTH statements,,,
