As shown below, an observer (o) is located 400 ft from a building (b). the observer notices a knife (k) flying at a 29 degrees angle of elevation from his line of sight. what equation and triganomic functiom can be used to solve for the height (h) of the knife? what is the height of the knite? you must show all work and calculations to receive full credit.

tangent  =opposite/adjacent

221.72 deg

Step-by-step explanation:As shown below, an observer (o) is located 400 ft from a building (b). The observer notices a knife (k) flying at a 29 degrees angle of elevation from his line of sight. What equation and triganomic functiom can be used to solve for the height (h) of the knife? What is the height of the knite? You must show all work and calculations to receive full credit.

from the statement, we can deduce that

the opposite is the height of the knife, 29 deg is the angle of elevation

the adjacent distance to the building is 400ft

You will use the tangent of angles

tan =opposite/adjacent

angle is =29deg

the adjacent of the angle is 400ft in this case

so =h/400

400

221.72 deg

tan 29° =

400 tan 29° = h

221.7 = h

221.7 ft

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
