An astronomer knows the distances from herself to stars AA and BB, as well as the distance between them. The distances are 450450, 400400, and 9090 light years respectively.
If the astronomer's telescope is currently pointed at star AA, how many degrees must she rotate her telescope to see star BB?
Round your answer to the nearest degree.
what i did
and they got 10 degrees...
Aliaa and Zhang Li are tennis-playing robots capable of placing shots with superhuman precision.
Aliaa is about to hit its next shot to the far corner of the court. It (Aliaa) knows that the distance between itself and Zhang Li is 520\cm, and it knows that the angle between Zhang Li and the far corner is 53 degrees
. Similarly, Zhang Li knows that the angle between Aliaa and the far corner is 100 degrees
What distance should Aliaa hit the ball so that it lands perfectly in the far corner of the court?
Round your answer to the nearest centimeter.
So what i did
but Khan Academy says 1128 cm....
So, I assume you guys know about ARBTheEpic? right? well, anyway
He has a twitter profile, named, GeniusIsBack aka A.R.B/
https://twitter.com/geniusisback also, we found him
Intrestingly, he has posted very little posts on other sites,while posting over 500 posts on here.
Also, it proves he's not a robot, but rather an insane man that posts wherever.
