Answer:
x = 18
y = 15
Explanation:
The two lines that are parallel tell us that x is 18 because there is a 90-degree angle. 90° / 5 = 18, so x must be 18.
The y is a bit more complicated, but still fully solvable. "All quadrilaterals' interior angles sum to 360°" so we can find y by doing the following:
Equation: 90° + 90° + (4y - 10)° + 5(y + 11)° = 360°
Distribute: 90° + 90° + 4y - 10° + 5y + 55° = 360°
Combining like terms: 225° + 9y = 360°
Subtracting 225 from both sides: 9y = 135°
Divide both sides by 9: y = 15
I hope this helps, have a nice day :D
