Answer: , II,
<u>Step-by-step explanation:</u>
a)
Add 2π until you receive a positive number. 2π =
+ =
+ =
b) < < π So it is located in Quadrant II
c) It is closest to the x-axis at π. π - =

Answer: π, (-1, 0), A, 0
<u>Step-by-step explanation:</u>
a) -7π
Add 2π until you receive a positive number.
-7π + 2π = -5π
-5π + 2π = -3π
-3π + 2π = -π
-π + 2π = π
b) Look at the Unit Circle to find that π is located at (-1, 0)
c) x = -1, y = 0, r = 1
sin θ =
d) sin θ = = = 0

Answer: 7π
<u>Step-by-step explanation:</u>
s = rθ
= 35
= 7π
