Answer: For each question simply look at the angle mark. For 4, 5, and 6, it is a 90 degree angle. Simply subtract-
4. 90-22= 68, then divide by 4 which would give you 17. X= 17
5. 90-65= 25, then subtract 2. X= 23
6. 90-43= 47, then subtract by 7. X= 40
For questions 7-9, the angle is 180. Simply do the same thing but use 180 instead of 90.
10. The angle is 90 degrees, same as 4-6, just fill in the equation with the new numbers
11. X=16 . 92+78=164, 180-164
12. Sorry will answer this soon, have to get to school
Hope I helped :)
