Question

The diagram below shows an angle, 0, graphed in the xy -coordinate plane. Segment RT is the initial side of the angle, and segment RM is the terminal side. Segments RT
and RM are radii of the unit circle centered at the origin R (0,0).

The x-coordinate of point M is -1/2. What is the measure of 0 to the nearest thousandth of a radian.

Answer 1

Answer:

Step-by-step explanation:

for this problem u need the unit circle.

In the unit circle there is a point with -1/2 as the x value that is at 240 degrees.

then you convert 240 degrees to radians --> 240 X pi/180 = 4.189

the unit circle is below, you needa remember for the test

Good luck on your EOC, i'm doing it too
