Question

faces 5 edges 9 find vertices ​

Answer 1

Question :-

faces 5 edges 9 find vertices ​ ?

To find :-

Vertices

Solution :-

$\texttt{Here\:we\:have\:to\:find\:vertics\:so\:by\:Adding\:2}\\\texttt{\:in\:number\:of\:edges\:and\:subtract\:the }\\\texttt{number\:of\:faces\:.}$

For example

$\mathsf{we\:have\:2\:faces\:and\:8\:edges\:}?\\\\\texttt{Solution:-}\\\\\bold{2\:+\:8\:=\:10}\\\\\bold{10\:-\:2\:=\:8}\\\\\bold{so\:now\:the\:vertices\:are\:8}$

Your question :-

faces 5 edges 9 find vertices ​?

Solution :-

$\mathsf{9\:+\:2\:=\:11}\\\\\mathsf{10\:-\:5\:=\:5}\\\\\texttt{so\:vertices\:are\:5}$

Final Answer

$\boxed{\mathsf{Vertices\:=5}}$
