Answer 1

ANSWER

Let the number of sides of triangle be n

Then measure of each interior angle =

n

(n−2)×180

Measure of each exterior angle = 180−

n

(n−2)×180

=

n

360

According to question , ratio of exterior angle to interior angle = 2:7

So , solving we get n=9 and each exterior angle=40
