Answer:
x = 60
Explanation:
The shape shown in the image is a hexagon. The sum of interior angles in a hexagon can be calculated with the following formula:
(n-2) × 180
- (n is the number of angles)
4×180 = 72
- Now we need to add all given angle measures to find x
100 + 125 + 100 + 2x + 140 + 3x - 45 = 720
5x + 420 = 720
- Subtract 420 from both sides
5x = 300
x = 60
