Question

if face=20 and vertex=12,then value of edge is​

Answer 1

Answer:

$according \: to \: formula \: \\ v - e + f = 2 \\ so \: by \: putting \: the \: value \: of \: f = 20 \: and \: v = 12 \: in \: formua \: \\ 12 - e + 20 = 2 \\ 32 - e = 2 \\ - e =2 - 32 \\ - e = - 30 \\ e = 30 \\ so \: number \: of \: edges \: is \: 30$

➡️ $\huge\bf\orange{Given :-}$

➡️ face = 20

➡️ vertex = 12

$\huge{By~formula}$

$\huge{V~-~e~+~f~=~2}$

${put~"f"~and~"v"~value~in~above~equation}$

➡️$\bf{12~-~e~+~20~=~2}$

➡️$\bf{32~-~e~=~2}$

➡️$\bf{-~e~=~2~-~32}$

➡️$\bf{-~e~=~-~30}$

➡️$\bf{e~=~30}$

$\bf{value~of~edge~=~30}$
