Hii subodh,see let`s draw a median from A to BC which touches GH atP and BC at Q.ok.then see AQC is 90°.and BQ=CQ.from properties of isosceles triangle.so AC=13 n CQ=5 given. So AQ=12. Let AP=x.so...
it is a simple formula which is useful to know the trigonometric ratios, and their values. it explains the behavier of trigonometric ratios in coordinate plane.

compound interest is A = P (1 + r/n) nt Hence given, 618 = P (1 + r) 2 and 600 = P*r*2/100 dividing both we get, 618/600 = (10(1+r)/r)^2 we get r= 3% approx.
co-efficient of x^10 will be 1 co-efficient of x^9 will be sum of roots co-efficient of x^8 will be sum of roots taken 2 at a time hence ans= 1.2 +2.3+3.4 +...........+ 9.10 Now you can find this...
Sec^3theta/tan^2theta +cosec^3theta/cot^2theta because sec^2theta-1=tan^2theta after this put sectheta =1/costheta and tantheta=sintheta/costheta. And cosectheta=1/sintheta and....

@SAMBIT,THE ANSWER POSTED BY ME WAS 15/24 WHICH IS REDUCED TO 5/8 THEN WHY IS IT DISAPPROVED?THE ANSWER IS DEFINITELY CORRECT WITH PROPER AND METHODICAL EXPLANATION
real numbers includes the all rational numbers,but rational numbers is express that p/q format here q is not equal to 0,Natural numbers are all positive numbers.
cos^2 1 + cos^89= 1 (cos 89= sin1 ) similarly upto cos^44 + cos^2 46 = 1 ( coss 44= sin 46) i.e; (cos^2 1 + ...cos ^ 90)= 44 + cos^2 45 + cos ^2 90= 44.5
Sorry Unrecognised. Check the attachment please! Not relevant to question! Re – post again on the forum.
We know that there are 4 kings and 4 queens in a deck Hence, the remaining number of cards= 52-(4+4)=44 a) Number of red face cards=2 i.e 2 jacks PROBABILITY= 2/44=1/22 Number of black cards=26-4=22 ...
This will occur when p is negative or when p=0. Therefore the required probaility is 4/7, since out of the seven numbers, only -3, -2, -1 and 0 satisfy the condition.

@meenu yes , osswal is a good book to start with , but as far as class 10 th are concerned , then first u have to do ncert each and eevry question alongwith solved examples , that is your main...
Number =899*quotient+63. Numbar =29*31*quotient+2*29+5. So the reminder obtained by dividing the number by 29 is 5
@ mukilan i can give u the correct approach for this question . kindly solve that the two equation will be given to you in the question , step 1 = try to find out the slope of the line by comparing...
See ac=h,ab=h/2so ac=3½/2 so from trigonometry knowledge angleDBC=30°.then draw a perpendicular to CE .let point be F .so angleEAF=angle DBC.=30°thenAF=BC=3½/2so find...
Dear student, Whats the question? What do we have to find out ? Thanks
When U would find te common difference between each term U would get 1.1 that s constant. thus d = 1.1 a1 = 1.2 an = a1 + (n-1)*1.1 = 1.2 + (n-1) . simlarly apply the formulae for summmation n nterms ...
