Answer:
x = 40 degrees
Step-by-step explanation:
We are given that AB and CD are parallel to each other and they are cut by a transversal.
The angle 40 is complementary to angle z, so this means that they have the same measure by the complementary angles theorem.
Complementary are angles that occupy the same space on one parallel line compared to the other parallel line.
Angle z = 40 degrees
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The area of a sector with measure  in degrees is given by
 in degrees is given by  , where
, where  is the radius of the sector.
 is the radius of the sector.
What we're given:
Solving, we get:

*Notes:
- units should be in square meters (area) 
- the problem does not say whether to round or leave answers in term of pi, so you may need to adjust the answer depending on what your teacher specifically wants
 
        
             
        
        
        
Since they are just next to each other ill take it multiplication and that would be 128 if its not let me know and ill correct it
