Marko is playing the video game Fort Attack. The purpose of the game is to shoot invading bandits that are trying to breach the fort's circular wall, and Marko must provide the angle at which the cannon should turn in order to shoot the attacking bandits. The bandit is attacking as pictured in the figure.

What is the angle of fire in standard position on the unit circle in both degrees and radians?

your zero degree mark is your positive x axis (points at 3:00). Add your degrees counter-clockwise from that point. Each quarter is 90 degrees. You have two quarters plus 30 degrees less in your 3rd quarter. 90+90+(90-30)=total degrees.

im sorry but I dont see 240 as an answer
these are the only answers offered
 120°; pi over 6 radians

 120°; 2 pi over 3 radians

 30°; pi over 3 radians

 30°; 2 pi over 3 radians

120deg does = 2pi/3 and 30deg = pi/6

anonymous · Answer

so the only one that is right that you listed is 120deg 2pi/3. I don't know why 240 is not an answer.

anonymous · Answer

did you mean to say one of the answers was 30 deg pi/6?
