Plllzzz me will give ! what is the value of x? enter your answer in the box.

The interior angles of a 7 sided figure add up to 900o That's because if you pick any vertex of an angle and draw diameters so that you create triangles, you will get 5 triangles. In general the interior angles will add up to (n - 2)*180 where n is the number of sides of a polygon.

So the simple way to do this is to equate the seven angles + x to 900

Equation

x + 125 + 126 + 158 + 120 + 139 + 121 = 900

Solve

x + 789 = 900  Subtract 789 from both sides.

x = 900 - 789

x = 111  <<<<< answer

what do you mean by fog

step-by-step explanation:

452,489 to the nearest thousand is 452,000
