Answer: x = 117 degrees.

Step-by-step explanation:  The sum of the interior angles of a pentagon should equal 540 degrees. The value of x has to make the total of the angles equal to 540.  140 + 138 + 59 +86 is 423.  Now we need to subtract 423 from 540 to know the value of x since it has to all add up to 540. 540-423 is 117.

Answer:

117°

Step-by-step explanation:

sum of angles of a polygon=(n-2)*180

where n is the number of sides.

it has 5 sides.

x+86+140+138+59=(5-2)*180

x+423=3*180

x=540-423

x=117°
