Answer:
117°
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°
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.
