Question

The angles of a pentagon are x 0 , (x+20)0 ,(x+40)0 ,(x+60)0 and (x+80)0 . Find the angles of the pentagon.​

Answer 1

Step-by-step explanation:

Given angle of pentagon are x,x+20,x+40,x+60 and x+80

We know that sum of angle of pentagon =5400

Then x+x+20+x+40+x+60+x+80=540

⇒5x+200=540

⇒5x=540−200

⇒x=5340=68o

Then smallest angle of pentagon is 68o
