The value of x given that the sum of exterior angle is 360 is 27
<h3 /><h3>Sum of exterior angle of a pentagon </h3>
Sum of exterior angle of a pentagon is 360°. Taking the sum of the angles and equating to 360 degrees, we will have:
2x - 20 + 2x + 50 + 3x + 10 + 3x + 50 = 360
Collect the like terms
10x + 90 = 360
Subtract 90 from both sides
10x + 90 - 90 = 360 - 90
10x = 270
x = 27
Hence the value of x given that the sum of exterior angle is 360 is 27

Supplementary angles is when 2 angles add up to 180 degrees.
We will name the smaller angle a and the bigger angle b.
therefore:
b - 172.6 = a
a + b = 180
Now we substitute:
a + b = 180
b - 172.6 + b = 180
2b - 172.6 = 180
2b = 352.6
b = 176.3
To find a:
a + b = 180
a + 176.3 = 180
a = 3.7
Therefore,
angle a = 3.7 degrees
angle b = 176.3 degrees.
Hope it helps and have a great day ahead

Please would you mind marking me as the brainliest:)
Step-by-step explanation:
f(x)=x^2+x
so
f(x-1) = (x - 1) ^ 2 + (x - 1)
= x^2 - 2x + 1 + x - 1
= x^2 - 3x
and
f(x+1) = (x + 1) ^ 2 + (x + 1)
= x^2 + 2x + 1 + x + 1
= x^2 + 3x + 2
now
f(x-1) + f(x+1) = 6
x^2 - 3x + x^2 + 3x + 2 = 6
2x^2 = 4
X = √2
