Answer:

82

Explanation:

This is a 7-sided figure meaning it's interior angles add up to...

(7-2)*180=5*180=900 degrees

We can use this information to set up an equation:

x+2x+160+125+110+147+112=900

Combine like terms:

3x+654=900

Subtract 654 from both sides:

3x+654-654=900-654

3x=246

Divide both sides by 3

x=82
