Answer:
141
Step-by-step explanation:
The interior angles of a polygon with <em>n</em> sides is 180(<em>n</em> - 2) and the polygon has 7 sides, so the sum of its interior angles is 180(7 - 2) = 180(5) = 900.
125 + (x + 7) + 107 + (x - 15) + x + 131 + 122 = 900
Combining like terms,
3x + 477 = 900
3x = 423
x = 141
703+620≈1320
first you have to round 703 to 700, because it's an estimation, then you can add 700 to 620, and it'll be easier than 703+620.
I think is on the mile 3 just look at the example:
I am not sure if I am correct, but I hope I am :)
The answer to this is
1.9 - tenth
1.94 - hundredth
1.938 - thousandth
