Question

A plane which bisects the angle between the two given planes 2x – y + 2z – 4 = 0 and x + 2y + 2z – 2 = 0, passes through the point:
(A) (1, 4, -1) (B) (2, -4, 1)
(C) (2, 4, 1) (D) (1, -4, 1)

Answer 1

Answer:

c

verify experimentally hope it helps

Answer 2

A plane which bisects the angle between the two given planes 2x – y + 2z – 4 = 0 and x + 2y + 2z – 2 = 0.

• The plane bisects the angle between the given planes as given.

• Taking the given equations as 1&2

• By solving the equations we get

(x,y,z) = (1,-4,1).

•So , option D is the right answer.
