- Answer: Step-by-step explanation: The equation of the given planes are :- 2x+y+3z=0 x-2y+5=0
- formula to find angles between two planes is :-
- cosФ = | a₁a₂ + b₁b₂ + c₁c₂ | / √ a₁² + b₁² + c₁² * √ a₂² + b₂² + c₂²
- so acc to this formula and putting the values of a₁ , b₁ , c₁ , a₂ , b₂ , c₂ we get the numerator as 0
- this shows that cosФ = 0
- so Ф=90°
- this shows that the planes are ⊥ to each other
