The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.

What is the value of x?

Enter your answer in the box.

x =

Answer 1

360=x+x+(2x+3)+(2x+3)
we have 360=2x+2x+2x+6
360-6=6x
354=6x
x=354/6=59
x=59

Answer 2

The value of x is
`59\°`

Explanation:

we know that

The sum of the internal angles of a quadrilateral must be equal to
`360\°`

so

`(2x+3)\°+(2x+3)\°+x\°+x\°=360\°`

solve for x

`2x+2x+x+x=360\°-6\°`

`6x=354\°`

`x=59\°`
