It would be simple division 5/3 = 1.66.
Answer:
<em>The distance from the flagpole to the tree is 27 ft</em>
Step-by-step explanation:
<u>Similar Triangles</u>
Since the elevation angle from which the trees cast their shadows has the same measure and given the tree and the flagpole and the ground form right angles, both triangles are similar.
Similar triangles have their corresponding side lengths proportional. The ratio between the distances from the bench to the tree and flagpole and their heights is constant, i.e.:
![\displaystyle \frac{16}{18}=\frac{40}{x}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B16%7D%7B18%7D%3D%5Cfrac%7B40%7D%7Bx%7D)
Where x is the distance from the bench to the tree.
Solving for x:
![\displaystyle x=40\cdot \frac{18}{16}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x%3D40%5Ccdot%20%5Cfrac%7B18%7D%7B16%7D)
x = 45 feet
Thus the distance from the flagpole to the tree is 45 - 18 = 27 feet
<h3>
Answer: 10%</h3>
Work Shown:
2/20 = 0.10 = 10%
Note that 10% of 20 = 0.10*20 = 2 dollars is the sales tax to help confirm the answer.
Answer:
m = 10
Step-by-step explanation:
According to the picture attached, we can see the angles formed.
The angle on the top (5m+100) is sided with the angle 2m+10. This means that they are supplementary angles, their sum is 180°.
So,
5m+100+2m+10 = 180
5m+2m=180-100-10
7m = 70
m = 10
