Question

In the given five sided closed figure,find angleEAB+angleABC+angleBCD+angleCDE+angle DEA. ​

Answer 1

Answer -  540°

explanation:  

• We are asked ∠EAB+∠ABC+∠BCD+∠CDE+∠DEA which are actually all the angles of this polygon

   so using the formula (n-2)*180   where n is no. of sides

   applying the formula =>     (5-2)*180 =>   540°
