Question

2x+y+3z=0 and x-2y+5=0 what is the angle between the planes?

Answer 1

Answer:the answer will be 0

Step-by-step explanation:

Answer 2

• 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
