Question

2. The sum of angles of a convex polygon with number of sides 7 is
a) 900°
b) 1080
c) 1440°
d) 720°​

Answer 1

Explanation:

a) 900°

mark me as brainlest

Answer 2

Given:n=7 [ where is number of side of convex polygon]

We know that sum of angles =(n-2) =180

Hence, the angle sum of the convex polygon =

(7-2)= 180 = 5×180° = 900°
