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?

h = 221.72 feet

Step-by-step explanation:

From the picture attached,

Observer 'O' is 400 feet from a building 'B'.

Observer notices a kite is flying at an angle of elevation of 29° from his line of sight.

For the height of the kite,

By applying tangent rule in ΔOBK,

tan(29)° =

0.554309 =

0.554309 =

h = 400 × 0.554309

h = 221.72 feet

Therefore, height of the kite is 221.72 feet.

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.
