Answer 1

@bibby hey could you help please?

Answer 2

I believe the formula for total degrees is 180 x (n-2)
wher n = the number of sides that the polygon has.
so 180 * 5 = 900

And then you can add up the various angles and make it equal 900 to find x

Answer 3

@bibby thats exactly what I did, thank you :)
