I think it is the middle one becuase complimentary angles add up to 90 degrees and if one is 8 less than the other it would be proved like that.
If this was a triangle, the answer would be 35 degrees. Can you plz show a graph if you have one though?
The Table shows a rate of 3 miles per hour. So you would multiply the number of hours times 3.
1 x 3 = 3
2 x 3 = 6
4 x 3 = 12
6 x 3 = 18
Time (hours) Miles
1 3
2 6
4 12
6 18
Hope this helps :)
The final answer is c! Hope I helped :)
