I mean 450.... mistake

Another problem

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?

^\circ

∘

Round your answer to the nearest degree.

Well

what i did

I got

76 degrees...

and they got 10 degrees...

sorry i just noticed same file

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

and then

resulting in

416*2=832

but Khan Academy says 1128 cm....

any hel=p?

fails with geogebra

youtube profile.

Intrestingly, he has posted very little posts on other sites,while posting over 500 posts on here.

why??

Also, it proves he's not a robot, but rather an insane man that posts wherever.
