Answers : (3)

										x2+y2+2gx+2fy+c=0

condition for orthogonal,
2*g*10=c+4
perpendicular fron center to x=2 is radius..
f2=22g
put g=-x and f=-y
hence,y2=-22x

Is it correct because one way it says m1/m2 is +ve and ax1+by1+c)/(ax2+by2+c) To negative
 
 
Dear Student, Correction is there, On solving the equation, we get – m1/m2. So negative sign is missing over there. Thanks.

TRIANGE ABC IF ANGLE A =X,ANGLE B=3x-2AND ANGLE C=Y AND ANGLE C- ANGLE B=9.FIND THREE ANGLES
 
 
Hint, Using the conditionANGLE C- ANGLE B=9, we can find that angle C = 7 + 3x. So the three angles in terms of x will be A = x and B = 3x-2 and C = 7 + 3x. Thanks

out of 2^1/2 and 3^1/3 which is greater
 
 
Take log on both sides, you will get ½ * log2 and 1/3 * log3. If you put values of log2 and log3, you will get 1/3 * log3 > ½ * log 2.
