Answer:
The measure of the missing angle x is:
Step-by-step explanation:
Let 'x' be the missing angle of a Pentagon
Given that the sum of four angles in a pentagon is 440°.
We know that:
- The sum of internal angles in a simple pentagon is 540°.
Thus,
we get the equation such as:
sum of four angles + x = 540°
440° + x = 540° ∵ sum of four angles = 440°
subtract 440° from both sides
440° + x - 440° = 540° - 440°
x = 100°
Therefore, the measure of the missing angle x is:
