## anonymous one year ago As shown below, an observer (O) is located 400 feet from a building (B). The observer notices a kite (K) flying at a 29° angle of elevation from his line of sight. What equation and trigonometric function can be used to solve for the height (h) of the kite? What is the height of the kite? You must show all work and calculations to receive full credit.

where is the drawing ?

3. anonymous

no drawing :/

4. ganeshie8

The question starts with `As shown below,...` could you double check there is really nothing below the question ?

5. anonymous

srry there is XD

6. ganeshie8

First go to the given angle corner and stare at the triangle : |dw:1433975815718:dw|

7. ganeshie8

Opposite side = ? Adjacent side = ?

8. anonymous

opposite side = 193.92 adjacent side = 349.84

9. ganeshie8

how did u get those ?

10. anonymous

sine and cosine of 29 is that right?

11. ganeshie8

Not quite, just look at the triangle : |dw:1433976213716:dw|

12. ganeshie8

|dw:1433976275063:dw|

ohhh

14. ganeshie8

Which trig ratio involves both Opposite and Adjacent sides ?

15. anonymous

tangent?

16. ganeshie8

Yes use that

17. ganeshie8

\[\large \tan(29)~=~\dfrac{h}{400}\]

18. anonymous

221.72

19. ganeshie8

Correct!

20. anonymous

thank you! how do you give medals on this???

21. ganeshie8

Do you see blue medal button next to my rely ?
