Question

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.

Answer 1

Here's some more trig for you! Which trig function uses the opposite side and adjacent side?

Answer 2

Tangent

Answer 3

Good. What's your equation then?

Answer 4

Tan29=h/400?

Answer 5

That's right :)

Answer 6

Now I have to solve to find the height, but I'm not sure where to start

Answer 7

Multiply both sides by 400.

Answer 8

You'll get h by itself.

Answer 9

(400)Tan29=h

Answer 10

Yep. What would your answer be?

Answer 11

221.72362058=h

Answer 12

Sounds right to me. :)

Answer 13

Yay I have 2 more questions, I'll post and tag you :)

Answer 14
