Answer 1

Answer:

The value of x is $59\°$

Step-by-step 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

$2x+2x+x+x=360\°-6\°$

$6x=354\°$

$x=59\°$

Answer 2

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
