Answer:
x = 115° , y = 65° , z = 115°
Step-by-step explanation:
The figure is a parallelogram.
Consecutive angles are supplementary ( sum to 180° ) , then
x + 65° = 180 ( subtract 65° from both sides )
x = 115°
Opposite angles are congruent , then
y = 65°
z = x = 115°

Answer:
- ∠AOD ∠BOC = 49°
- ∠AOB = ∠DOC = 131°
Step-by-step explanation:
Pick any pair of angles and write the equation that expresses their relationship. Solve for x, then use that value in any of the angle expressions to find the corresponding angle value.
For example, ...
∠AOD + ∠AOB = 180°
(5x -1) +(9x +41) = 180
14x = 140 . . . . . collect terms, subtract 40
x = 10 . . . . . . . . divide by 14
Now the angles are ...
∠AOD = (5·10 -1)° = 49°
∠AOB = (9·10 +41)° = 131° . . . . . supplementary to 49°
The remaining linear or vertical angles are equal to one or the other of these.
