Answer:
x = (270° - 9y°)/2
y = (270° - 2x°)/9
Step-by-step explanation:
The sum of angles in a quadrilateral is 360°
The angles in the quadrilateral above are: 3y°, 6y°, 2x° and 90°
2x° + 3y° + 6y° + 90° = 360°
2x° + 9y° = 360° - 90°
2x° + 9y° = 270°
2x° = 270° - 9y°
x = (270° - 9y°)/2
2x° + 9y° = 270°
9y° = 270° - 2x°
y = (270 - 2x°)/9
