A equation of diameters of the circle x2 + y2 - 12x + 4y + 6 = 0 is given by

 
x + y = 0
x + 3y = 0
x = y
3x + 2y = 0

If two distinct chords drawn from the point (p, q) on the circle x2 + y2 = px + qy (where pq 0) are bisected by the x-axis, then

 
p2 = q2
p2 = 8q2
p2 < 8q2
p2 > 8q2
Please type your answer before submitting.

Kindly give the solution.

Let the triangles ABC and DEF be inscribed in the same circle. If the triangles are of equal perimeter, then

 
cosA + cosB + cosC = cosD + cosE + cosF
sin2A + sin2B + sin2C = sin2D + sin2E + sin2F
the areas of the two triangles are the same

I think second and fourth option is correct
