Question

Examine the table
What can you say about the angle sum of a convex polygon with number of sides 7

• A. ${900}^o$
• B. ${980}^o$
• C. ${1080}^o$
• D. ${720}^o$

Answer 1

The correct option is A ${900}^o$

From the given table, clearly we observe that the sum of angles (interior angles) of a polygon with n sides = $\left(n2\right){180}^o$
Here n=7
The sum of the angles of a polygon of 7 sides
= $\left(72\right){180}^o={5180}^o={900}^o$
