Answer:
21
Step-by-step explanation:
since its a rectangle there are two lengths of six. If you add them together you get 12. subtract the total perimeter of 54 by the 12 and get 42. Since there is 2 sides left divide by 2. You should get 21 for the width of the rectangle
Answer:

12
Note:
Since there is no y value m can not be determine. Therefore finding the sum here can not be determined so instead you can try simplifying
Answer: 140
Step-by-step explanation: since 4 = 40 then 2 would also be 40 because they are the same angle (Keep in mind that a line is 180 degrees) 180-40=140! Good luck! :D
