Find the correct statement(s)?
A) the lines x + log b(base a).y + log c(base a) = 0, log a(base b).x + y + log c(base b)= 0 and log a(base c).x + log b(base c).y + 1 = 0 are concurrent
B)Equation of a straight line passing through origin and making with x axis an angle twice the size of the angle made by the line 5y = x with the x-axis is 5y = 2x
C) The triangle formed by 2x - y + 5 = 0, x + y - 5 = 0 and x - 2y - 5 = 0 is isoceles
D) None of these.
Hello, fardeen_gen!
Ah, masters explained (B) and (C) . . . good!
A very challenging problem!Find the correct statement(s).
Using the Base-Change Formula:A) The lines: . . . . . True
The lines are identical . . . They are concurrent.
. . (They share a common point.)
