For this special angle, draw the angle and find the reference angle: t= 2π/3
Nezavi [6.7K]

Answer:

C.  And the reference angle is pi/3

Step-by-step explanation:

Let me give you a little quick way to do this. You’re probably trying to memorize the unit circle and figure out what 2pi/3 equals. However, all you need is a bit of math.

Start with the denominator and multiply  the numerator by its correct  angle

Anything with 3 in it’s denominator, is a multiple  of a 60 degree angle. The numerator is 2 so do 60 x 2, which equals 120. Your angle is 120 and will land in the top left quadrant.

Moving on to the reference angle. Think of this as being what you have left on the  horizontal axis. The angle took up 120 degrees. Now find the rest. 180 - 120 = 60. Pi/3 equals 60 degrees

To find the area of the shape which is the shaded area I assume: we must find the sum of the area of the rectangle AECD and triangle BEC

   Total Area =area of rectangle AECD + triangle BEC

                     = 9 * 15 +  (1/2) * 6 * 15 = 136 + 45 = 181 square milimeters
