Question :-
ABCDE is a star. Find the value of
angle ( A+ B+ C +D+ E )
​

Answer 1

ANSWER.. .. {∆}

THERE IS A IMPORTANT FORMULA OF THE SUM OF ANGLE IN ANY POLYGON WHICH IS GIVEN BELOW.. .. . {¶}

$sum \: of \: all \: the \: angles \: of \: the \: polygon \\ of \: side \: n \: is \: given \: as \: (n - 2)180 \\ \\ verification..... \\ \\ take \: a \: triangle \: we \: know \: that \: the \\ sum \: of \: all \: the \: angle \: is \: 180...let \: prove \: it \\ \\ n = 3(for \: triangle) \\ (n - 2)180 \\ (3 - 2)180 = 180 \ \\ : hence \: verified \\ \\ the \: no \: of \: side \: of \: your \: figure \: is \\ 10 \\ \\ so \: sum \: of \: all \: angle = (10 - 2)180 \\ (8)180 = 1440$

Answer 2

I know the Answer of this Question:—

since, there is 2 triangle in a star,

sum of angle of a triangle= 180°

Then sum of 2 triangle = 360°

A+B+C+D+E= 360°
