Answer:
No student is wrong.
Step-by-step explanation:
No student is wrong. Coterminal angles are angles with same initial side and terminal side. Coterminal angles θc of angle θ and can be found by
If θ =60°
Coterminal angles would be:
Answer:
Because -13 < 10, so -13 is farther from 0 than 10
Answer:
5:40
Step-by-step explanation:
This is a problem involving the least common difference.
If you know that the red and blue trains left at the same time at 5, you know that another red train will leave at 5:08. Another blue train at 5:10.
The way to solve this will be to write out the factors of 8 and 10 and find the smallest number that they overlap.
Red:
8, 16, 24, 32, 40, 48, 56, 64, 72, 80
Blue:
10, 20, 30, 40
You see that after 40 mnutes, they are both leaving the station again. After 40 minutes, at 5:40, they are both leaving.
You would have open circles at 3 and 6.
x < 3 so the line will go from 3 to the left.
x > 6 so the line will go from 6 to the right.
