Answer:
140 + 360n, for any integer n
Step-by-step explanation:
Coterminal Angles of an angle are the angles who share the same initial side and terminal sides of that angle,
The coterminal angle of an angle is obtained after adding or subtracting the multiple of 360°,
That is, If we have an angle Ф,
Then its coterminal angles are Ф + 360n,
Where, n is an integer,
Here, Ф = -220°,
Thus, the coterminal angles are,
(-220 + 360n )°,
Where, n is an integer,
If n is an integer ⇒ n + 1 is also an integer,
Thus, the coterminal angles of -220° are,
(-220 + 360(n+1) )°
= ( -220 + 360n + 360 )°
= (140 + 360n)°, where n is an integer.
LAST option is correct.
