Answer: X= 30
Step-by-step explanation: So I must admit that is a really weird place to put that line, but if this is a complementary angle and the first angle is 30 degrees, then the other angle should be 60 degrees. 60/2 is 30, so therefore x=30
1. (3,-2)
2. (-2,2)
3. (1/3,2/3)
4. (13/7, 40/7)
If functions transfer some a to b via some formula, then inverse of such functions transfer b to a via some other formula.
Hope this helps.
