The value of x according to the information given about the trapezoid is; 5.375
<h3>Isosceles trapezoid</h3>
The sum of angles in a trapezoid like other Quadrilaterals is; 180°.
However, since the trapezoid is Isosceles, Top angles are equal and bottom angles are equal too.
Hence, we have;

You do 9+3 which equals 12 then you multiply that by 4
The Law of Cosines is used for this purpose.
c² = a² + b² - 2ab·cos(C)
c² = 5² + 4² - 2·5·4·cos(60°)
c² = 25 + 16 - 20 = 21
c = √21
The length of side c is √21 ≈ 4.583._____
If you really intend the side lengths to be 55 and 44, your result is c≈50.408, the above value times 11.
Answer:
(x,y)=(2,-1)
