Question

a pentagon all side is X find the value of x​

Answer 1

Answer:

in the pentagon we have 5 sides, and if each side is x then 5 x x =5x

the sum of 5 sides in a pentagon =540

5x=540

x= 540/5

x=108

verification:

108 *5 =540

Answer 2

Answer:

X = 540°

Step-by-step explanation:

Given that ,

a pentagon all sides angle is "x" .

To find the value of "x".

So,

a pentagon  has five sides .

By using the formula ,

( X - 2 ) 180°  , where "X" is the number of sides.

Therefore,

 X = ( x - 2 ) 180°

 X   = ( 5 - 2 ) 180°

 X   = 3 × 180°

 X   = 540°

All sides angle is equal to 540°.

Angle of each sides = 540°/ 5

                                = 108°

From the above result , we know that a pentagon has 5 sides and

each sides angle is 108° and all side angle is ( 5 × 108° ) = 540°.

Formula to find angle of polygons of X sides.

=> ( x - 2 ) × 180 °
