Question

solve the following questions​

Answer 1

$\small \bold{1.The \: exterior \: angle \: of \: a \: regular \: polygon \: is \: \frac{360}{n} }$

Given, 45°

Side (n)

$⇒ \frac{360}{n} = 45$

$\huge { \red{ \mapsto \cancel \dfrac{360}{45} = \boxed{\tt 8}}}$

⇒n=8

3-Since,

sum of all exterior angles is 360 degrees,

Therefore,

90+60+50+x+90=360 (Linear pair theorum)

290+x=360

x=70
