Question

The angles of a pentagon are z0, (z+20)0, (z+40)0, (z+60)0 and (z+80)0. The smallest angle of the pentagon is.

Answer 1

Here's your answer...

Given,

Angles of Pentagon are

z, (z+20), (z+40), (z+60) and (z+80)

We know that,

Sum of all angles in a Pentagon is 540

z+z+20+z+40+z+60+z+80 = 540

5z+200 = 540

5z = 540-200

5z = 340

z = 340/5

z = 68

The smallest angle is 68
