Answer:
<h3> To find x you need to divide polygon into triangles</h3><h3>The formula
: "the sum of exterior angles=360°" is false for concaved polygons</h3>
Step-by-step explanation:
α = 180° - 135° = 45°
β = 180° - 120° = 60°
γ = 180° - 60° = 120°
δ = 180° - x
ε = 180° - 80° = 100°
If we divide the pentagon into five triangles then:
5•180° = α + β + γ + δ + ε + 4x
900° = 45° + 60° + 120° + x + 100° + 4x
900° = 325° + 5x
5x = 575°
x = 115°
60° + 120° + 135° + 80° + 115° = 510° ≠ 360°
Answer:
x=11,10,9,8,7,6,5,4,3,2,1,0, and all the negative numbers could be subsituted for x
Step-by-step explanation:
2 (l + w) = 36
l + w = 18
2x + 7x = 18
9x = 18
x = 2
the length of the sides
l = 2x
l = 2(2)
l = 4
w = 7x
w = 7(2)
w = 14

<u>Note</u>:-
- A fraction is said to be written in its lowest form if its numerator and denominator are prime, that is, they have no common factors other than 1.
On desmos, a graphing calculator, I inputted your numbers, and I got that each side is 11 units long. Therefore, because a hexagon has 6 sides, you would have 6 * 11 = 66 units.
Therefore, your answer is 66.
Hope this helps and have a nice day:)
