The angle between 0° and 360° that is coterminal with -160° is 200 degrees.
<h3>What are coterminal angles?</h3>
Two different angles that have identical starting and ending edges are termed coterminal angles however since one angle is measured clockwise and the other is determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.
It is given that:
The angle is -160 degrees
An example of a positive coterminal angle would be 360-160=200 degrees since angles always travel either counterclockwise or clockwise from the +x axis.
There can be an unlimited number of rotations and hence infinite coterminal angles because there is no range.
= -160 + 360 = 200 degrees
= 200+ 360n
= -160 - 360n degrees
Thus, the angle between 0° and 360° that is coterminal with -160° is 200 degrees.

Answer:
<u>The measure of the arc CD = 64°</u>
Step-by-step explanation:
The rest of the question is the attached figure.
It is required to find the measure of the arc CD in degrees.
as shown at the graph
BE and AD are are diameters of circle P
And ∠APE is a right angle ⇒ ∠APE = 90°
∠APE and ∠BPE are supplementary angles
So, ∠APE + ∠BPE = 180°
∠BPE + 90 = 180°
∴ ∠BPE = 180 -90 = 90° ⇒(1)
But it is given: ∠BPE = (33k-9)° ⇒(2)
From (1) and (2)
∴ 33k - 9 = 90
∴ 33k = 90 + 9 = 99
∴ k = 99/33 = 3
The measure of the arc CD = ∠CPD = 20k + 4
By substitution with k
<u>∴ The measure of the arc CD = 20*3 + 4 = 60 + 4 = 64°</u>
