Asurveyor measures the angle of elevation to the top of a building to be 70 degrees. the surveyor then walks 50 ft farther from the base of the tower and measures the angle of elevation to be 50 degrees. the surveyor's angle-measuring device 5.5 ft from the ground. how tall is the building, to the nearest foot?

height of building,H = 5.5 ft + 105.2 ft = 111 ft to the nearest ft.

Step-by-step explanation:

in this question we have given angle of elevation=

when surveyor walks 50m farther from the base of the tower that time angle of elevation=

As shown in figure in triangle ABD

.............(1)

or h=2.74x

and in triangle ABC

...........(2)

put value of h in equation 2

we got,

therefore,

Height of the tower is,h=2.74\times 38.39ft

h=105.2ft

Therefore,

height of building,H = 5.5 ft + 105.2 ft = 111 ft to the nearest ft.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
