Answer:
w = 30
y = 13
z = 10
x = 90
Step-by-step explanation:
The sum of the interior angles of a quadrilateral add up to 360°. Keeping that in mind, we can solve for the variable of w, y, z, and x by setting their given angles to 90° since there are 4 angles within the rectangle.
3w° = 90°
w = 90/3
w = 30
(5y + 25)° = 90°
5y = 90° - 25°
5y = 65°
y = 13
9z° = 90°
z = 90°/9
z = 10
x° = 90°
x = 90
