6) From a point on the ground 15 ft. From the base of a flagpole, the angle of elevation of the top of the pole measures 57°. Ho
w tall is the flagpole?
1 answer:
Answer:23.1 ft
Step-by-step explanation:
Given
Point is 15 ft away from the base of the flagpole
The angle of elevation is ![57^{\circ}](https://tex.z-dn.net/?f=57%5E%7B%5Ccirc%7D)
from the figure, we can write
![\Rightarrow \tan 57^{\circ}=\frac{Y}{15}\\\\\Rightarrow Y=15\times \tan 57^{\circ}=23.09\approx 23.1\ ft](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctan%2057%5E%7B%5Ccirc%7D%3D%5Cfrac%7BY%7D%7B15%7D%5C%5C%5C%5C%5CRightarrow%20Y%3D15%5Ctimes%20%5Ctan%2057%5E%7B%5Ccirc%7D%3D23.09%5Capprox%2023.1%5C%20ft)
The length of the flagpole is 23.1 ft

Answer:
V=11*7*9=693
Step-by-step explanation:
V=Bh ( B is the base area ( base*height) , and h is the height of the prism)
find B=base*h
B=11*7=77 in²
V=B*h=77*9=693 in³
Answer:25°
Step-by-step explanation:
tanθ= 35/72
It would be: 6 1/2 - 5 1/2
You can check by simplifying:
= 13/2 - 11/2
= 13-11/2
= 2/2
= 1
