Which represents the measures of all angles coterminal with a 400 angle

C. 40 + 360n, for any integer, n

Step-by-step explanation

Conterminal angles are angles in standard position that have a common terminal side. For example, 30, -330 and 390 are all coterminal. This is to say that -305 angle and a 415 angle are coterminal with a 55 angle. For all angles coterminal with 400 angle, 40 + 360n , for integer , n will give the correct measure.

correct answer:

b.(19,-2)

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
