Yes, you want to find x take a close look and see if u knw(can knw) any other sides in that triangle ?

4. highschoolmom2010

|dw:1376252547785:dw| using the drawing i got 16 idk if its right

5. ganeshie8

thats right ! 15 ft radius + 1ft overhang = 16

6. ganeshie8

keep going

7. highschoolmom2010

sorry 1 sec

8. ganeshie8

ok

9. highschoolmom2010

$\cos (25)=\frac{ 16 }{ x }$

10. highschoolmom2010

i have forgotten what to do next

11. ganeshie8

you wanto find x

12. ganeshie8

maybe multiply x both sides first

13. highschoolmom2010

$(x)*\cos25= \frac{ 16 }{ x }*(x)$ $X \cos 25=16$

14. ganeshie8

next ?

15. highschoolmom2010

$\frac{ X \cos 25 }{ \cos 25 }=\frac{ 16 }{ \cos 25 }$

16. ganeshie8

perfect !

17. highschoolmom2010

$x=14.5$

18. ganeshie8

try again

19. ganeshie8

looks uve multiplied cos25, instead of dividing

20. highschoolmom2010

16.1

21. ganeshie8

try again

22. highschoolmom2010

*breaking out scientific calculator*

23. highschoolmom2010

approx 17.6

24. ganeshie8

lol, yes 17.65 ft but they want the answer in ft and inch

25. highschoolmom2010

ok so i convert ???

26. highschoolmom2010

the .65 is confusing me

27. ganeshie8

17.65 ft 17 ft + .65 ft 17 ft + .65 x 12 inch ?

28. ganeshie8

17.65 ft 17 ft + .65 ft 17 ft + .65 x 12 inch 17 ft + 7.8 inch 17 ft 7.8 inches ~ 17 ft 8 inches

29. highschoolmom2010

wow i feel kinda bad for not knowing that :(

30. ganeshie8

its tricky lol

31. highschoolmom2010

oh yea

32. ganeshie8

instead of doing all this conversion thingy, we could have simply converted 16 ft to 16x12 inches in the starting itself, and taken the ratio !

34. ganeshie8

when free, you can try this.... skip for now :)

35. highschoolmom2010

ok thanks :D

36. ganeshie8

actually both are equal. we have to convert anyways in the end, so forget it !

37. highschoolmom2010

oh ok
