Question

Find the number of polygon of sides if each exterior angle is equal to twice its adjacent interior angle

Answer 1

Answer:

So number of sides=3

Step-by-step explanation:

Let the interior angle =x

then exterior angle= 2x

We know that sum if int angle nad ext angle =180

so x+2x=180

3x=180

x=180/3=60

so the interior angle =60

and we know the interior of equilateral triangle is 60

hence n=3

So number of sides=3
