Which of the following statements is not true concerning radian measure? select the correct choice below.
a. an angle in standard position having a radian measure of theta equals negative startfraction 5 pi over 3 endfraction has a terminal side that lies in quadrant i.
b. an angle in standard position having a radian measure of theta equals negative startfraction 11 pi over 6 endfraction has a terminal side that lies in quadrant iv.
c. one radian is the measure of a central angle that has an intercepted arc equal in length to the radius of the circle.
d. one radian is approximately 57.3 degrees.

B

Step-by-step explanation:

Let's examine and comment on each alternative.

A. An angle with a measure of which is equivalent to -300º, will be traced in a clockwise way. As shown in the picture below. So the endpoint stops in the Quadrant I. True

B. Since rad is also equivalent to -330º, it has a negative orientation which tells us that it will be traced in a clockwise way as well. But its endpoint will lie on Quadrant I. Not on Quadrant IV as the B affirms.

So the B item is False.

C. Keep in mind, that Radian is a unit of measurement taken when you have an arc subtended from a unit circle with arc length 1

As shown in the picture below. True

D. If you consider the 1 Circle and its circunference, which is 2, (360º) we can just make this simple division:

= 180º/3.1415.. ≅ 57.3º   True

y > 1/3x

y < = -x + 4
