Question

Look at the hexagon shown.
What is the value of x?

90

140

65

110

Answer 1

The sum of angles in any polygon is (sides-2)180
This has 6 sides, so 4(180) = 720
Thus, we can assume that the sum of the angles = 720, so ..
x + (x+5) + (X+5) + x + 135 + 135 = 720
condense numbers and simplify to :
4x+10+270=720
subtract 280 from both sides
4x=440
divide by 4
x=110

Ask if I need to clarify :)
