Ineed to solve for x of this shape.

So for a shape with a certain amount of sides, there will always be a fixed number for the internal angles.

For example, a triangle must have 180 degrees of internal angles.

A square must have 360.

The formula therefore is, (if s equals the side number)

180(s - 2)

And s here is 6

So,

180 * 4

Or, 720

So all those numbers need to add up to 720.

So we can just add up these.

160 + 75 + 108 + 113 + 132

Or, 588.

Now since we know they have to add up to 720, but we only have 588, we need to figure out how much more we need.

720 - 588 = 132

So x = 132.
