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.

    if oyu look at angle O - how would you name the side h with respect to O would it be Opposite Adjacent or Hypotenuse? how would you name the side 400 with respect to O would it be Opposite Adjacent or Hypotenuse?

    look at the diagram is h opposite or adjacent to O

    so is o an angle? h is like a side, so I'm guessing it can't be opposites like they're not opposite angles so I'm gonna go w adjacent

    OK you are evidently studying triangles and the functions sin cos and tan you need to be able to identify the sides of a triangle opposite, adjacent and hypotenuse, with respect to a given angle. This is a basic requirement of doing these functions. Go back to your text or notes and find out how ot identify the sides THEN come back to this question

    OK GOOD So which of the 3 functions uses opposite and adjacent? and what is the formula using them?

    tangent = opposite/adjacent

    i keep getting a really big number i don't think its correct @MrNood

    so you were correct tan29 = h/400 so multiply each side by 400 what is tan(29)?

    OK - you have made a mistake with your calculator We have 29 degrees your calculator is set to 'radians' mode

    so your equation is now 0.55 = h/400 so what is h?

    yay!! ok its gonna come out to h=220

    OK - well done but you rounded to 0.55 is that accurate enough?
