3. Liltico

7. sritama

|dw:1342585190223:dw|

8. sritama

you can find the value of w from this equation.

9. Liltico

11. sritama

at first find tan 42 degree by using calculator , then divide 12 by it

12. Liltico

i got .07

13. sritama

tan 42=.07 ?

14. sritama

http://www.wolframalpha.com/.. use it..

15. Liltico

tan 42 is .9004040443

16. Liltico

then what would i do with that?

17. sritama

yeah, you can take it .9

18. sritama

now divide 12 by .9, you will get 13.33

19. Liltico

yeah

20. sritama

so, w=13.33

21. Liltico

thats W right

22. sritama

now find the value of tan 27

23. Liltico

ok so how would i find X

24. Liltico

ok

25. Liltico

.5

26. sritama

yeah, now the problem is |dw:1342585786815:dw|

27. sritama

solve for x

28. Liltico

10.2

29. sritama

10.67

30. Liltico

ok thanks

31. sritama

have you taken approximate value of .5 * 13.33 ?

32. sritama

if yes, then there may be some difference
