Question

Determine the value of x in this polygon.

Answer 1

Answer: X = 23.5

Explanation:

Answer 2

x = 23.5

Explanation:

It's the trapezoid.

We know: the sum of the angle measures at one leg of a trapezoid is 180°.

Therefore we have the equation:

`(x+12.5)+(6x+3)=180` combine like terms

`(x+6x)+(12.5+3)=180`

`7x+15.5=180` subtract 15.5 from both sides

`7x=164.5` divide both sides by 7

`x=23.5`
