Answer:
25 ft
Step-by-step explanation:
The diagram shows two triangles that are similar. Similar triangles have equal angles and sides that are proportional to each other. Since the base of each triangle is given, we can find the proportion of the sides:
![\frac{smaller}{larger}=\frac{8}{40}=\frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7Bsmaller%7D%7Blarger%7D%3D%5Cfrac%7B8%7D%7B40%7D%3D%5Cfrac%7B1%7D%7B5%7D)
Given the ratio of the smaller to larger triangle, we can set up a proportion to find the missing height of the larger triangle:
, where 'x' represent the height of the tree
cross-multiply: x = (5)(5) or 25 ft
Answer:
x = 14
Step-by-step explanation:
![\frac{150}{84} = \frac{25}{x} \\ \\ 150 \times x = 84 \times 25 \\ \\ x = \frac{84 \times 25}{150} \\ \\ x = \frac{84}{6} \\ \\ x = 14 \\](https://tex.z-dn.net/?f=%20%5Cfrac%7B150%7D%7B84%7D%20%20%3D%20%20%5Cfrac%7B25%7D%7Bx%7D%20%20%5C%5C%20%20%5C%5C%20150%20%5Ctimes%20x%20%3D%2084%20%5Ctimes%2025%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B84%20%5Ctimes%2025%7D%7B150%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B84%7D%7B6%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%2014%20%5C%5C%20)
If she made a 90 that means 90 percent aka .90 so multiply that by 60 to get 54 right aka 6 wrong which you could find either by subtracting 54 from 60 or solving for 10 percent bc she got that much wrong and multiply .10x60=6 wrong
