Question

In the given tulangle find the value of angles
x first sight angle X second side 50 degree third side 60 degree answer

​

Answer 1

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

We know that sum of angle of pentagon =540

0

Then x+x+20+x+40+x+60+x+80=540

⇒5x+200=540

⇒5x=540−200

⇒x=

5

340

=68
