Question

What will be the sum of all angles of a convex polygon which has 7 number of sides?

• A. ${900}^o$
• B. ${780}^o$
• C. ${820}^o$
• D. ${800}^o$

Answer 1

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

Sum of Interior Angles =$(n-2){180}^o$
Here n = Number of side =$7$
Sum of interior angles =$(7-2)\times {180}^o={900}^o$
