David is standing 500 feet away from the base of a cell phone tower. The angle of elevation from his eyes to the top of the tower is 78. If David's eyes are 6 feet above the ground, how tall is the tower?

Step-by-step explanation:

The trigonometric figure is presented below. The height of the tower is found by applying trigonometric functions:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
