@surajpandey ji ka fb mein post kara Q/A hai
X and Y are centres of circles of radii 9 cm and 2 cm respectively , XY =17 cm . Z is the centre of a circle of radious r cm which touches the above circles externally. given that angle XYZ = 90 degree . the value of r is.,,,,,,,,,,,,,,......options are:- (A) 13
(B) 6 cm (C) 9cm (D) 8cm
nahi yar maine toh abhi geo ka question post nahi kia? 😛 kaha hai

@surajpandey @coolparul007

For question 3, my suggestion is:-

anything related to that type of questions are meant to leave...jisme degree to radians mein convert karna ho... its calculative and take much time and efforts.

time bachega to wapas aa kar kar lena... jo ki I m sure nahi bachega.. so its my dearest suggestion. leave it!

ok...get ready for more question today nght..prep karlo thik se... ;)

Hahahaa... yes... I am talking about 1st question. 1/2 radian and 1/3 radian wala....

moreover tier-1 mein ek question poocha tha...simple degree to radian conversion type.... uske answers were like 2711 pi/ 8000 .....mein aaj bhi usko within 2 mins nahi solve kar sakta....

kindly check this ques here xzy = 90 deg angle xyz= 90 deg and still both circle touch not possible
here XY is hyp and sides will be (9+r) and (2+r). hyp pair of 8,15,17 fits so r = 6
u can also solve the full eq and get
400
for conversion

(deg/90) = (G/100) = (2*radian/pie)

yeh ques galat hai..........yeh representations wala ques hai jo SSC ko bhej rhe hain........bt diagram to ban skti hai make a 90 deg triangle n circles at 3 vertices........

Given :- Sinx = (rt3/ p) and Cosx = (1/p)

There is only one angle sin 60 = rt3/2 and also cos 60= 1/2

so value of p is 2.

Its a hunch but worked very well in this question.
