## anonymous 3 years ago A rocket travels 50 km vertically upward at a 90° angle from point A to point B. It then moves a distance of 50 km along the line segment BC, as shown below. What is the height of the rocket, at point C, from the ground? 90 km 75 km 80 km 85 km

oh man i hated those... dont you ave to the tan cos sin things?

3. anonymous

those are for angles I beleive...

4. anonymous

yea i just need the distance :;

5. anonymous

well its probably a special triangle... a 90,45,45?

6. anonymous

nope its not :l

7. anonymous

its a 90,60,30...

8. anonymous

so whats $x \sqrt{2} = 50km$

9. anonymous

well i dont know ... uhmmm i forgot all that stuff hold on let me work

10. anonymous

nvm its $x \sqrt{3} = 50$

11. anonymous

oh ok

12. anonymous

I have no idea how to solve that xd

13. anonymous

I'm thinking the answer is 75

14. anonymous

i think its aprox. 9.128709

15. anonymous

were did you get 75 ? lol i went to myalgebra.com and typed in x square root 30 = 50 and clicked solve lol thats what it gave me

16. anonymous

lol looking at the picture :D

17. anonymous

lol xD well my answer is wrong i guess or myalgebra.com is wrong xD

18. anonymous
