HELP FIND VALUE OF X

72

Step-by-step explanation:

5a = 540            [ all interior angles r equal to 540 as "(n-2)x 180  (Interior                                           angle poperty )]

a= 540/5 = 108   (one interior angle)

x + a = 180                      (linear pair)

x= 180 - a

x = 180 - 108 = 72

Another way ::

Sum of Exterior angle = 360                 (exterior angle property)

One exterior angle = x = 360 / 5 = 72        ( 360 by the number of sides )

I hope im right!1 Sorry if im wrong :((

step-by-step explanation:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
