Question 1
1 / -0

In the following case, determine whether the given planes are parallel orperpendicular, and in case they are neither, find the angles between them. 2x + y + 3z – 2 = 0 and x – 2y + 5 = 0

A
The planes are at 55^∘

B
The planes are parallel

C
The planes are at 45^o

D
The planes are perpendicular

Solution

We have ,2x + y + 3z – 2 = 0 and x – 2y + 5 = 0. Let θ be the angle between the planes, then
As a₁a₂+ b₁b₂+ c₁c₂=2(1) + 1(-2)+3(0)=0.
Therefore , the given planes are perpendicular to each other.
