## razor99 3 years ago A man watches a bird fly which is at a vertical height of 800km from the ground.If The angle of elevation is 60 Degree,find the actual distance between the man and the bird

k?

4. anonymous

so we need to find out what x equals

5. anonymous

Now are you aware of SOHCAHTOA?

6. razor99

yea

7. razor99

i know SOHCAHTOA :P

8. anonymous

Okkk so which one would you use if you need to find out what x is?

9. razor99

lol idk hahahhaa

10. razor99

Hypontneus right

Ok so whats opposite our angle 60 degrees?

13. razor99

hypotnuse

14. anonymous

Nope I labeled the hypotnuse

15. anonymous

if you see 800 is directly across the 60 degree angle

16. razor99

yea :D

17. razor99

so in here we should find the distance right

18. anonymous

Ok here is the answer tan(60)=800/x

19. anonymous

so x=800/tan(60)

20. razor99

13.3

21. razor99

is it correct

22. anonymous

Nope

23. anonymous

x=461.88

24. razor99

oh we should dvid by including tan right

25. anonymous

ya so its $$x=\large \frac{800}{\tan(60)}$$

26. razor99

oh okay so thats the final answer right

27. anonymous

yup:)

28. razor99

thank u swiisy

29. anonymous

np :)
