Step-by-step explanation:
A rational number is a number that can be expressed as a fraction so when you add 2 fractions it’s a rational number
Answer:

18. 150
19. 240
20. 20
21. 60
22. 240
23. 150
24. -240
25. 222
26. 75
27. 300
28. 340
29. 175
30. 265
31. 298
32. 118
Step-by-step explanation:
How you find co-terminal is by adding or subtracting 360 degrees to the value you are given.
If it is a positive number like #18. all you do is subtract 510 - 360 = 150 until you get to a value between 0 degrees and 360 degrees.
The same thing applies to negative numbers. Like #21. You will add 360 + (-660) until you get to a number between 0 degrees and 360 degrees.
-660 + 360 = -300 (this is not a value in between 0 and 360 so we must add 360 again)
-300 + 360 = 60 (this is a value in between 0 and 360) (this is the co-terminal angle)
That is the idea of finding co-terminal angles.
3(x+5)+2x
First, distribute 3 to all terms within the parenthesis
3(x) = 3x
3(5) = 15
3x + 15 + 2x
Combine like terms
(3x + 2x) + 15
5x + 15
(B) is your answer
