"A bullet is fired into the air at an angle of 45°. How far does it travel before it is 2,000 feet above the ground?"
I put 2,000 (feet) and it said "wrong". I put 2000 (feet) and it said "wrong"... WHAT?!
Edit: THERE IS ONLY ONE SIDE GIVEN. (h=2000, l=?)

Best ResponseYou've already chosen the best response.0sorry friend they ask us the distance cover by bullet so we have to find hyp,according to formula sin(theta)=prependicular/hypo

Best ResponseYou've already chosen the best response.2Another example of a goofy question. Where do they get the morons that come up with these? Most likely, they want the length of the hypotenuse of a 454590 triangle, when we are told the side(s) are 2000

Best ResponseYou've already chosen the best response.0irishboy i think you are considering things of very high level and i don't think it is this type of question,normally for short distance you can take the path of bullet straight,we need to find arc length for very long distances and if you read the question carefully they are asking the distance travelled by bullet not the distance of point when he is at 2000 hight,you might be right but i think they wanted to find us what i wrote above

Best ResponseYou've already chosen the best response.0I know the answer is 2,000. The issue is WHY WON'T THEY ACCEPT THAT ANSWER (comma or not)?! x_x

Best ResponseYou've already chosen the best response.2@kittiwitti1 you have a 454590 triangle. Because it has two angles that are equal, it has two sides that are equal (both are 2000) they are asking for the length of the hypotenuse (longest side) the length is \( 2000 \sqrt{2} \approx 2828.4 \) ft see (for example) http://www.regentsprep.org/Regents/math/algtrig/ATT2/Ltri45.htm

Best ResponseYou've already chosen the best response.0They're asking for how far it goes forward (horizontally) though aren't they? @phi

Best ResponseYou've already chosen the best response.2***A bullet is fired into the air at an angle of 45°. How far does it travel *** the bullet is going up (and forward) along the diagonal. This distance it travels is the length of the diagonal, 2000*sqr(2)= 2828.4 ft
