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\°

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
