The student is not correct.
For angles to be coterminal, the difference between their measures must be a multiple of 360°.
The difference between 180° and –180° is 360°.
Angles with measures 180° and –180° are coterminal.

Answer:
The length of DF must be between 21 and 53.
Step-by-step explanation:
In a triangle, the length of two sides added together must exceed the length of the 3rd side. So, since EF is the shortest of the two givens, we know that EF + DF must be greater than DE. So we can plug in these numbers to find the minimum.
EF + DF > DE
16 + DF > 37
DF > 21
Now, for the upper maximum, we know that the two given lengths must be greater than the length of DF. So again, we can solve for the maximum using the amounts.
DE + EF > DF
37 + 16 > DF
53 > DF
With these two in mind, we know that DF must be between 21 and 53
Answer: (2,-5.4)
When I reflect across the y axis I keep the sign of x the same but change the sign of y
For example: (1,2)=(1,-2)
Answer:
x = 10 so D
Step-by-step explanation:
-4 + x = 6
add 4 both sides to get the x by itself
so 4 + 6 = 10
then the final answer is x = 10
