Question

PLEASE help if you’re able!!

Answer 1

To find the sum of interior angles of this polygon you have to use the equation

S=180(n-2)

where n is the number of sides

S=180(6-2)

S=180(4)

S=720 degrees

The sum of all angles is 720 degrees

`110 + x + 25 + x - 30 + x + x + 115 = 720`

`4x = 720 - 110 - 25 - 115 + 30`

`4x = 720 - 220`

`4x = 500`

`x = (500)/(4) = 125`
