Algebra applications: find the value of x and y

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

∞ this is your sign

y=x+9
