The value of x in the shape is 111
How to determine the value of x?
The shape is a heptagon
This is so because the shape has 7 sides
i.e. n = 7
The sum of angles in the shape is
Sum = 180(n - 2)
So, we have
Sum = 180(7 - 2)
Evaluate
Sum = 900
Also, the sum of angles in the shape is
Sum = x + 120 + 158 + 126 + 125 + 121 + 139
This gives
Sum = x + 789
So, we have
x + 789 = 900
Evaluate the like terms
x = 111
Hence, the value of x in the shape is 111
