​

Answer 1

$\huge\boxed{\fcolorbox{black}{pink}{Answer}}$

$\: = 2× + 2× + × = 180 then , 5x$

$\: = 180 × = 180 ÷ 5 = 36 \: then \: the \: angle \: are \: 72 , 72 ,36$

$hope \: this \: helps$

Answer 2

$\huge{\boxed{\red{\bf{Answer:-}}}}$

Let the angle be -x

2x+2x+x=180

then,

5x = 180

x = 180 ÷ 5 = 36

then the angle are 72 , 72 ,

36=180

x=180÷5=36

Hence, the angle are 72,72,36
