$\frac{A_1+B_1+C_1}{A_2+B_2+C_2}$=0

TuteeHUB · Answer

$A_1+A_2+B_1 +B_2+C_1+C_2$=0

TuteeHUB · Answer

$A_1+B_1+C_1=A_2 B_2 C_2$

TuteeHUB · Answer

$A_1 A_2+B_1 B_2+C_1 C_2$=0

1.	If the planes \(A_1 x+B_1 y+C_1 z+D_1\)=0 and \(A_2 x+B_2 y+C_2 z+D_2\)=0 are at right angles to each other, then which of the following is true?
A.	\(\frac{A_1+B_1+C_1}{A_2+B_2+C_2}\)=0
B.	\(A_1+A_2+B_1 +B_2+C_1+C_2\)=0
C.	\(A_1+B_1+C_1=A_2 B_2 C_2\)
D.	\(A_1 A_2+B_1 B_2+C_1 C_2\)=0
